The Golden State Warriors lost Game 5 of the NBA Finals on Monday, and they may have lost their starting center as well after Andrew Bogut went down with a knee injury in the third quarter. After blocking a shot by Cleveland Cavaliers guard J.R. Smith, Smith fell into Bogut's left leg as they crashed to the floor.

Bogut's knee appeared to bend the wrong way and he crumpled to the floor in pain. There were a couple of possessions before the Warriors called timeout to get Bogut off the floor. Bogut was initially diagnosed with a left knee sprain and missed the rest of Game 5. He'll have an MRI Tuesday.

Bogut was immediately helped to the locker room and was putting no weight on his left leg.
