Things are heating up in the Eastern Conference.

After two losses in Boston, Chris Bosh is a game-time decision and might be a major reason Miami get passed the Boston Celtics in 2012 Eastern Conference Finals, which is tied a two games a piece.

Bosh, who has been absent since May 13 with a strained a lower abdominal muscle, has been an important contributor for the Heat this season, and Miami has had to rely on the scoring of LeBron James and Dwyane Wade in the big man's absence.

Meanwhile, the Celtics, who didn't surrender a loss in their two games at home, have found a way to put together a nice run despite lackluster efforts in southern Florida.

A key for the Celtics will be Rajon Rondo. The aggressive point guard is capable of putting up amazing statistics, and it will be up to Mario Chalmers to contain the Celtics' youngest weapon.

Game Five tips off about 8:40 p.m. in Miami. The game can be see on ESPN. It can also be watch on a live stream here.

PREDICTION: This should be a tight game for at least three quarters with or with Bosh in the lineup. Expect Boston to put more pressure on the low post on offense, and for Miami to use their perimeter advantage in the fourth quarter. Miami can't afford to lose at home, and should play Game Five with more urgency than the Celtics.

PREDICTED SCORE:  Heat over Celtics, 96-89
