Marcus Smart apparently wasn’t joking about being ahead of schedule.

The Boston Celtics guard has been out of action since suffering a torn oblique in early April. But Smart, who initially was expected to miss at least the first two rounds of the NBA playoffs, has a chance to play Monday night when the Celtics face the Milwaukee Bucks in a pivotal Game 4 at TD Garden.

The Celtics, trailing 2-1 in their second-round playoff series, will tip off with the Bucks at 7 p.m. ET.
