David Lee had 29 points and a season-high 20 rebounds and the Golden State Warriors beat the Trail Blazers 108-87 on Tuesday night, tempering the celebration as Portland secured a playoff spot.

Monta Ellis added 30 points for the Warriors, who led by as many as 26 points.

LaMarcus Aldridge had 17 points and 12 rebounds for the Blazers, who saw their eight-game winning streak at the Rose Garden end.

The Blazers clinched a spot in the playoffs just before the half when the Houston Rockets lost 104-101 to Sacramento.

It will be Portland's third straight trip to the postseason. Last year the Blazers were eliminated in the first round by the Phoenix Suns, and the year before they were bumped in the opening round by the Rockets.

The Blazers were sitting in the sixth spot in the Western Conference, a half-game ahead of New Orleans and a game up on Memphis.

The Warriors were previously eliminated from playoff contention. Golden State has not been to the postseason since the 2006-07 season.

The Blazers had a scary moment late in the first quarter when Marcus Camby stumbled awkwardly over Golden State's David Lee and tumbled with Lou Amundson under the basket.

Fans chanted "Mar-cus Cam-by" while the 6-foot-11 forward was seen to by trainers. He was eventually helped off the court and headed for the locker room.

The team said Camby sustained a neck strain and was questionable to return, although he did not.

Ellis hit a fadeaway jumper for the Warriors as time ran out in the first quarter to tie it at 19, before Aldridge hit a 19-foot jumper for the Blazers to tie it at 47 at the break. The first half had 14 ties and 14 lead changes.

Ellis gave the Warriors a 72-65 lead with a 3-pointer with 4:48 left in the third quarter. He added another one a short time later that made it 75-66.

The Warriors extended the lead to 92-72 on Lee's 21-foot jumper with 8:03 left. Both teams pulled out their starters down the stretch.
