Boston Celtics guard Marcus Smart has a foot sprain. David Butler II-USA TODAY Sports

The Celtics are listing guard Marcus Smart as questionable for Game 1 of the Eastern Conference Finals on Tuesday due to a right mid-foot sprain he sustained in Game 7 of the Eastern semifinals, the team announced Monday (via Twitter).

According to ESPN’s Adrian Wojnarowski (via Twitter), Smart underwent an MRI on his injured foot, and the imaging came back clean, which bodes well for the Celtics and the Defensive Player of the Year going forward. The hope, Wojnarowski says, is that Smart will be good to go for Game 1 vs. Miami, but the team will see how he feels on Tuesday before making a final decision.

In other Celtics injury news, Robert Williams will be available for the series vs. Miami with no minutes restrictions after missing the last four games of the Milwaukee series due to a bone bruise in his left knee (Twitter link).

Williams was technically active and available for Game 7 on Sunday, but head coach Ime Udoka said he didn’t want to adjust his rotation, per Tim Bontemps of ESPN (Twitter link).

Meanwhile, Heat point guard Kyle Lowry, who continues to battle a left hamstring injury, didn’t practice on Monday and appears unlikely to be available for Game 1, tweets Barry Jackson of the Miami Herald.

For what it’s worth, Jimmy Butler expressed confidence on Monday that Lowry is close to returning, telling reporters his teammate is in good spirits and remains engaged (Twitter link via Jackson).
