2300: Here's AP sports writer Graham Dunbar's roundup of tonight's EURO action.

WARSAW — Co-host Poland and Group A favorite Russia crashed out of the European Championship on Saturday, as the Czech Republic and Greece scored 1-0 wins to advance to the quarterfinals.

The Czechs won the group as a second-half goal from Petr Jiracek beat Poland, which wasted a series of chances early in the game in rainy Wroclaw.

Greece recaptured the spirit and style of its Euro 2004 title triumph to upset Russia, which led the group before kickoff.

Captain Giorgos Karagounis scored against the run of play with the final kick of the first half, and Greece hung on though an expected Russian onslaught that never came.

The streets of Warsaw were calm before Russia's return to action in the city four days after violent clashes with Poland fans.

2255: What are the odds on Angela Merkel and the Greek prime minister - whoever it may be - indulging in a spot of footballing diplomacy in Gdansk on Friday?

___

2250: Russia will look back upon that defeat and wonder how they lost. They had 25 shots, 10 of which were on target in comparison to the Greeks managing five attempts, of which two hit the target and most importantly, one hitting the back of the net.

___

2246: Tomorrow, we will find out who Greece and the Czech Republic will play in the quarterfinal. As group winners, the Czech Republic will play the runner up of Group B with Greece playing the winner. It is all still to pay for there, with every side having a possible route to the knock out stage when Portugal takes on the Netherlands and Germany plays Denmark. But tonight, the headlines are dominated by Greece and the Czech republic qualifying and co host Poland crashing out of the tournament along with Russia.

___

2244:So there you have it. Greece beating Russia is the shock result of the evening and the Greeks are jubilant in the National Stadium. Russia had so much of the ball but clear cut chances were few and far between, Alan Dzagoev going closest with a glancing header. The Russian fans are in tears but their pain is nothing compared to that of co host Poland. The players applaud their fans, who created such a vociferous atmosphere before kick off but now, all the cheers comes from the Czech corner of the stadium. They are through to the last eight with Greece.

___

2240: The Czechs are euphoric, Poland is distraught. Still time left in Warsaw between Greece and Russia though and Greece leads 1-0.

___

2237: RESULT: GREECE 1 RUSSIA 0. Greece qualify, Russia eliminated.

2235: RESULT: CZECH REPUBLIC 1 POLAND 0. Czechs qualify, Poland eliminated.

___

2224: Russia coach Dick Advocaat is throwing everything at Greece now. Pavel Progebnyak and Marat Izmailov have been brought on, joining Roman Pavlyuchenko in a front three for Russia in a desperate attempt to score and remain in the competition.

___

2220: Nervous times for Poland fans. Their side has fifteen minutes to score twice and remain in the tournament. They are losing 1-0 thanks to that Petr Jiracek goal for the Czech Republic and the co host must win to go through.

___

2217: Alan Dzagoev has received a booking too, for Russia and the joint top scorer of the tournament will miss the quarterfinal if they go through. Which as it stands, they don't.

___

2217: In Warsaw, Girgos Tzavelas steps up and curls a free kick against the bar for Greece. That could have sealed it for them!

___

2215: As it stands Greece and the Czech Republic are through to the quarters; Russia and Poland are out.

___

2214: Is this it for the co host Poland? Petr Jiracek receives the ball on the left of the penalty area , darts inside a Polish defender who is thrown off balance and slips to the ground and Jiracek pokes the ball beyond Tytan and into the far corner of the net. The Czechs will qualify for the knock out stage if they hold on, along with Greece.

___

GOAL! CZECH REPUBLIC 1 POLAND 0 (Jiracek)

___

2207: Greek striker Fanis Gekas is replaced by Jose Holebas., a defender, for Greece.

___

2204: In Warsaw, Greece's Karagounis takes a tumble in the penalty area. The referee, Jonas Eriksson of Sweden, instantly blows his whistle, gets out the yellow card... and shows it to Karagounis for diving. Good decision from the referee as replays show the Greece captain kicked the leg of the defender and threw himself to the ground. He is livid at the decision and misses the next match through suspension for being booked twice.

___

2202: Free kick to the Czech Republic on the edge of the left hand side of the penalty area. Wasilewski brings down Limbersky.

___

2200: I'm afraid Karagounis' goal has been the only real bright spot in either match. As I write this, Russia's denisov lets rip with a 20-yard shot that goes just wide of Petr Cech's goal. Poland have yet to carve out a chance in the early stages of the second half. Meanwhile in Warsaw, Russia has enjoyed plenty of possession but are finding the Greek defense difficult to break down. Greece looks happy to sit back and defend its 1-0 lead, judging by how it has set out in the second half.

___

2153: Some of Poland's tackles are becoming a little agricultural and Scottish referee Mr. Thompson will need to be firm.

___

2150: Eugen Polanski of Poland has been booked for a late sliding challenge. The co host is looking very fired up in the early stages of the second half.

___

2148: Roman Pavlyuchenko has replaced Aleksandr Kerzhakov at half time for Russia and begins the second half.

___

2140: There are some very nervous looking home fans at the Municipal Stadium. Poland, as it stands, is out of Euro 2012, unless they can secure a win in the second half against the Czech Republic.

___

2140: The onus is on co host Poland to attack in Wroclaw, as they know they must win to go through. But that last ditch goal from Greece in Warsaw means that as it stands, Greece and Russia both qualify for the knock out stage and both teams at the Municipal Stadium go home. The Czech Republic must score in the second half if things between Russia and Greece stays the same. Russia has been the better side in Warsaw but sloppy defending from Zhirkov sees Greece have the lead at the half time break.

___

2140: That Karagounis goal could, just could, set up a Greece vs Germany quarterfinal match which would pit the financial haves of Europe against the have-nots.

___

2135: That's a great finish by the Greece captain Karagounis! Zhirkov, who has done so well going forward, lapses in his defensive duties and Karagounis gets ahead of him on the left of the penalty area to blast a fierce, low drive that arrows past Malafeev and into the far corner. The Russia goalkeeper could have done better. In the other match, Czech Republic and Poland head into the dressing rooms level at 0-0.

___

2132: GOAL! GREECE 1, RUSSIA 0 (Karagounis)

___

2128: Three minutes to go until halftime.

(at)PhillipsIan: Greece holding its own vs. Russia at Euro 2012. Last in group, but a win could set up politically-charged quarter final clash with Germany. (via Twitter)

GREECE VS. RUSSIA: Zhirkov nearly breaks the deadlock for Russia. He receives the ball from a short corner and shapes to cross, but instead knocks it past a defender and unleashes a great shot that flies just over.

___

2118: GREECE VS. RUSSIA: Russia goes close again in Warsaw, where it's a lovely summer's evening and the stadium roof is open. Arshavin plays the ball into the center and fellow forward Kerzhakov is waiting to prod home, but the Greek defense clears.

___

2112: Still 0-0 in both matches.

CZECH VS. POLAND: Actually, the weather appears to be getting worse in Wroclaw. There were just rumbles of thunder and flashes of lightning. There's not going to be another suspension, is there? The players are absolutely soaked!

___

2105: CZECH VS. POLAND: It's raining in Wroclaw, but nothing like the downpour we saw in Donetsk on Friday for the France vs. Ukraine match. The Czechs have managed to take the sting out of a bright start from Poland.

GREECE VS. RUSSIA: Russia captain Arshavin tries his luck with a low shot from outside of the penalty area, but drags it wide.

___

2100: CZECH VS. POLAND: Lewandowski misses a great chance to give Poland the lead! On a quick break, Obraniak picks out the run of the striker in the penalty area and he holds off the challenge of Gabre Selassie but slices his left-foot shot wide. He should have tried to shoot across Cech there. That was a great chance to give the co-host a dream start.

GREECE VS. RUSSIA: Kerzhakov goes close now for Russia, which has come back into the game. Dzagoev tries to burst into the penalty area but he's blocked off by the Greek defense. The ball bounces out to Kerzhakov, who hits the ball on the bounce and it slowly curls wide of the far post.

___

2055: GREECE VS. RUSSIA: Early attempt for Greece through Katsouranis. He runs to the near post to flick the ball on from a corner and the ball loops toward the Russia goal. Goalkeeper Malafeev gets a fist to it at the last moment, pushing it away. The Greeks have started the brighter — remember, they have to win to go through.

___

2050: We are up and running. Both matches are make-or-break — one team will go through and one will go out in each game. After two matches, Russia is top of the group on four points, the Czechs three, Poland two and Greece one.

___

2044: And here are the teams for Greece vs. Russia:

Greece: Michalis Sifakis, Vassilis Torosidis, Sokratis Papastathopoulos, Kyriakos Papadopoulos, Giorgos Tzavelas, Yiannis Maniatis, Giorgos Karagounis, Kostas Katsouranis, Dimitris Salpingidis, Georgios Samaras, Fanis Gekas.
