"Bucks center Andrew Bogut hit his head on the Bradley Center floor in the second half Thursday and could not pass a league-based concussion test on Friday.

So the 7-foot Bogut will not be available for the Bucks' game against Dallas on Friday night at American Airlines Center.

Bogut was in Dallas at the team hotel but not at the arena.

Coach Scott Skiles said Drew Gooden would start at center. Gooden started in four games on the Bucks' recent western trip after Bogut had to leave due to a family medical issue in Australia."
