"Andrew Bogut was healthy and Bucks coach Scott Skiles was talking earlier Wednesday about ways to increase the big man's scoring production a few points a game.

Then it happened, without warning late in the first quarter of the Bucks' game against the Houston Rockets on Wednesday night.

Bogut went up to try to block a shot by Rockets guard Kyle Lowry and came down on Lowry's foot. The 7-foot center twisted his left ankle and limped off the court with the help of Bucks trainer Marc Boff.

After the game, Bogut sat in front of his locker with a grimace on his face and a large black boot on his left foot.

"It wasn't good," Bogut said. "I knew when I came down I was in some trouble. Keeping optimistic, everything's fine with the X-ray, but that's to be expected. I know I didn't break a bone."
