The Chicago Bulls will be fighting to regain home court advantage Friday night when they hit the road for Game Three of their playoff series against Atlanta. But they may have to do without one of their star players.

The Chicago Bulls Twitter feed had some bad news for fans this morning: Carlos Boozer, one of the top defensive players in the league, may not be able to play in Friday’s Eastern Conference Semi-Final game due to an injury to his right toe.

The Bulls are tied with the Hawks in the second round of the NBA playoffs, at one game a piece. They won in Chicago earlier this week. But tonight the Bulls play their first road game of the series. Tipoff is at 6 o’clock central time.

They’ll play again in Atlanta on Sunday. If Chicago makes it to the Eastern Conference Finals, they’ll face either Boston or Miami.
