The Celtics clash with the Bulls in the pivotal Game Five of their first-round series tonight at TD Garden.
The Celtics evened the best-of-seven set at two games apiece with a 104-95 win in Chicago on Sunday.
The road team has won the first four games in a playoff series for the first time since 2005.
Bulls guard Rajon Rondo is making an effort to play in tonight's game.
Rondo held a workout last night to see if he's healthy enough to be back on the floor for Game Five.
Rondo hasn't played since suffering a thumb injury in Game Two.
