Nicolas Spolli scored in the second half as Catania held Serie A leader AC Milan to a 1-1 draw at the Stadio Massimino on Saturday.
Robinho scored late in the first half for Milan, but Spolli's goal in the 57th gave Catania a share of the points and extended its undefeated streak to eight games.
Milan is also unbeaten in eight straight Serie A matches, but had its six-game win streak in league play snapped. Milan pushed its lead over Juventus to five points, but its unbeaten title rivals host Napoli on Sunday.
Robinho scored the first goal when Zlatan Ibrahimovic sent him through and the Brazilian slotted a low shot to the corner past Catania goalkeeper Juan Pablo Carrizo.
Catania responded through Spolli, who directed a Nicola Legrottaglie headed pass into the net past Milan goalkeeper Christian Abbiati from close range on the only shot on goal for his side.
Milan will switch focus to the second leg of its Champions League quarterfinal series against Barcelona on Tuesday in Spain. Milan and Barca tied the first leg at the San Siro, 0-0, last week.
Parma 3, Lazio 1
Parma, Italy - Sergio Floccari scored a brace as Parma downed Lazio, 3-1, at the Stadio Ennio Tardini on Saturday to snap an eight-game winless streak and climb eight points clear of the relegation zone.
Parma entered the match in 17th place, just one above the drop zone, but went ahead early on a goal from McDonald Mariga and Floccari added his first of the match in the 12th.
Lionel Scaloni pulled a goal back before half for Lazio, but Floccari secured an important win for Parma when he completed his brace in the 72nd.
Lazio lost for the third time in its last four and stayed in third place, but could slip to fifth Sunday when Napoli and Udinese are both in action.
Parma surged to 13th with eight matches left in the season.
