Marcus Smart hasn't played a game since he injured his oblique April 7 against the Magic.
The Celtics could be getting one of their starters back in the rotation. Marcus Smart told reporters Sunday, "The boxes are being checked," in reference to his return from an April oblique injury, according to Tim Bontemps of ESPN.com.
On Monday, the team announced he is available to play in Monday's Game 4 in Boston. Head coach Brad Stevens said Smart will come off the bench and is available to "play short stints."
Jaylen Brown has started all seven of Boston's playoff games to this point in Smart's place.
Smart said he was "feeling good" after taking part in practice with the squad Sunday. He was cleared for contact Saturday and he "took a charge on accident" during a three-on-three game.
"It was ironic because that's what I needed to do," Smart said. "And it just happened on its own, natural, it felt fine. Like I said, we'll see how today goes and check it out tomorrow."
Smart said he's "trying all kinds of things to get hit," so he can properly tell just how well his body recovered from the injury.
The Celtics are down 2-1 in their second-round series against the Bucks after losing the last two games.
"We're taking it one day at a time, but we're definitely in the right position, right time, progressive phase to where I'm getting really close to coming back here," Smart said.
