Kendrick Perkins played the final three games of the NBA Finals with a torn groin, league sources tell Yahoo! Sports.

This would explain a lot about Perkins' lackluster performance at times. We'll give Perk credit for gutting through what sounds like a very painful injury, but this emphasizes the fact that Scott Brooks should have used more of Nick Collison rather than continuing to trot Perkins out there. There is no word yet on if Perkins will require surgery.

Kendrick Perkins made 7-of-9 FGs in 33 minutes on Saturday, finishing with 15 points, nine rebounds, one block and three turnovers.

Perkins at less than full strength certainly raises some red flags, but most expect him to play in Game 3 on Friday. Perk played 31 minutes on Wednesday and was a big asset in helping to defend Andrew Bynum. Nazr Mohammed will also chip in with front-court minutes for OKC as they try to take a commanding 3-0 lead on Friday night.

He wasn't on a minutes count or said to be limited, but he went up for a dunk and was clearly in pain when he came back down.

Perkins' health could be central to this series, as the Thunder need him to control Andrew Bynum and Pau Gasol inside (something the Nuggets could not do in Game 7).
