Thunder PF/C Nick Collison did not play on Sunday because of poor matchups.

Collison is healthy and it's somewhat odd that OKC would have dropped a multi-year extention into the lap of a backup big man with such matchup-based limitations. Regardless, he's not a fantasy asset.

Nick Collison's new four-year extension is worth just over $11 million, sources tell ESPN.com.

Collison is getting a big signing bonus, but they are really just taking advantage of a big loophole to stay in good shape with the salary cap. He is not viewed as anything more than a rotational big man.

Thunder signed C Nick Collison to a contract extension.

Collison is a big body and insurance in case Nenad Krstic goes down. His contract was set to expire at the end of this season.

Nick Collison saw 34 minutes of action against the Bucks on Saturday, scoring six points on 1-of-6 shooting with six rebounds, no assists, and a steal.

He would not have seen so much time had Serge Ibaka not gotten into foul trouble, and Nenad Krstic (bone bruise in leg) been fully healthy. He is not a fantasy option until further notice.

Thunder big man Nick Collison returnded from a lower leg stress reaction against the Spurs on Sunday, notching two points and three rebounds in 11 minutes off the bench.

Collison missed training camp and was making his season debut, and it could be a while before he's truly up to speed. When he checked into the game he received a standing ovation from the classy fans in Oklahoma City.

Nick Collison had an MRI taken on the stress reaction in his left leg last week, and the results that came back were "good."

All this means is that he hasn't had any setbacks, since there is still no timetable for his return. His absence has cleared a few minutes for Serge Ibaka, and it's unclear at this time if he would be able to get those minutes back based on Ibaka's strong play so far.

Thunder big man Nick Collison could miss the first three weeks of the season with a stress reaction in his left leg.

"It's a little frustrating because it's a bone that has to heal," said Collison. "We're taking MRIs. We're using that information. We're also using how I feel. It's not an exact science." The 30-year-old PF/C feels that he could play through the pain, but OKC has little incentive to risk further injury at the start of the season.

Nick Collison remains sidelined with a bone bruise in his left knee.

Collison is "getting better every day," according to beat writer Darnell Mayberry, but it remains unclear when he'll be ready. He'll likely return to a backup role once he's healthy enough to play.

Nick Collison will miss the beginning of Oklahoma City's training camp because of a bone bruise in his left knee.

Collison had arthroscopic right knee surgery this summer, and now he's dealing with two banged up knees. He's a marginal fantasy player but once healthy he should be a lynchpin for the Thunder's frontcourt.

The Associated Press reports that Nick Collison underwent successful arthroscopic surgery on his right knee Tuesday.

Collison is expected to be able to begin rehab immediately and should be able to return to basketball activities this summer. All indications are that the surgery shouldn't affect his availability for training camp in the fall.
