Nikola Vucevic has moved from out to questionable for Sunday's matchup against Toronto, one month after finger surgery. The Celtics center missed substantial time since arriving from Chicago in a trade. Vucevic's return would provide Boston with additional frontcourt depth as they push toward the postseason.

The 15-year NBA veteran has appeared in just 12 games for Boston, averaging 10.4 points and 7.2 rebounds in 21.7 minutes. His potential return comes as the Celtics also bolstered their roster by signing Ron Harper Jr. to a new two-year deal Saturday. Harper has split time between Boston and their Maine G League affiliate this season.

Harper, son of former NBA player Ron Harper, has been part of the Celtics' rotation at times. The front office continues to adjust their roster amid Vucevic's recovery. Boston sits in a competitive position in the Eastern Conference with both players now potentially available to contribute down the stretch run.
