"Trail Blazers center Marcus Camby said he is in "a lot of pain" and unable to put weight on his left ankle after it rolled during the second quarter Friday night in San Antonio.

Camby said he will not play Saturday in Houston and is doubtful for Monday's game in New Orleans after X-rays revealed the injury is a sprain.

Blazers coach Nate McMillan said he hasn't decided on a starting lineup for Houston, but said he is leaning toward moving LaMarcus Aldridge to center, Gerald Wallace to power forward and inserting Nicolas Batum as a starter at small forward. Veteran Kurt Thomas will also be considered as a starter and likely will see a spike in playing time.

Camby suffered the injury with about 4:25 left in the second quarter when he drove the lane and put up a shot. As he landed near the foot of Spurs guard Kawhi Leonard, his ankle rolled. Replays were inconclusive, and Camby was unsure if he landed on Leonard's foot.

"I thought I was going to be able to get up and walk it off, but now I can't really put a lot of weight on it,'' Camby said. "There's just a lot of pain.''

It's a difficult loss for the Blazers because as McMillan said after the game, Camby "is the backbone of the defense." He is the team's best rebounder, smartest defender and is a heady passer. He is also one of the team's best leaders, exemplified by his status as co-captain."
