The Celtics (43-31) remain in the fifth seed in the Eastern Conference, but they're headed toward the postseason with anything but momentum. Boston has now dropped four straight contests, with their most recent loss a 115-96 defeat at the hands of the San Antonio Spurs on Sunday evening.

The Celtics will list Jayson Tatum (back) and Al Horford (knee) as questionable for Tuesday's contest. Robert Williams (back) will be listed as doubtful.

The Cavaliers (19-55) were long ago eliminated from playoff contention, although they continue to play spoiler on occasion down the stretch. Cleveland is a respectable 2-2 over its last four games, but they were manhandled by the Milwaukee Bucks, 127-105, in their most recent contest Sunday. Kevin Love posted a 20-point, 19-rebound double-double that also included three assists and one block. Jordan Clarkson poured in 19 points and added four assists and three rebounds.
