Michigan vs. Louisville rebound action aprox 50 seconds left

[hoopguy]

With about 50 seconds left in the game, Louisville shot with the shot clock about to expire. In live action on TV, it looked like Michigan player Trey Burke got pushed and knocked down on the rebound and he may have been pushed into the Michigan player who got the rebound and landed out of bounds.

I only saw the play once and not sure if there was a foul or not. None was called. At the time Michigan was down by 4 points and shooting the double bonus. Did others think there was a foul or good no call?
