The Cleveland Cavaliers take on the Boston Celtics at TD Garden on Tuesday night in Game 1 of their Eastern Conference semifinal-round series.

The Cavaliers (4-3 postseason) have just completed a knockdown, drag-out quarterfinal-round battle with the Orlando Magic, which they bested by a 106-94 score in Sunday afternoon's Game 7 at Rocket Mortgage Fieldhouse. Donovan Mitchell led the Cavaliers with 39 points, adding nine rebounds, five assists, one steal and one block. Caris LeVert furnished 15 points, five rebounds, four assists, one steal and one block. Max Strus delivered 13 points, three rebounds, one assist and one steal. Darius Garland supplied 12 points, four assists, three rebounds and three steals. Evan Mobley generated an 11-point, 16-rebound double-double that included one assist and five blocks.

The Cavaliers will list Jarrett Allen (ribs) as questionable for Tuesday's game. Dean Wade (knee), Craig Porter (knee) and Ty Jerome (ankle) will remain out.

The Celtics (4-1 postseason) will open the series with a significant rest advantage, as they last took the floor Wednesday night in their 118-84 walloping of the Miami Heat in Game 5 of their quarterfinal-round series. In the series-clinching victory, Jaylen Brown and Derrick White co-led the Celtics with 25-point, two-assist tallies while adding six and five rebounds, respectively. Sam Hauser supplied 17 points, five rebounds and one assist. Jayson Tatum generated a 16-point, 12-rebound double-double that included three assists and one block. Jrue Holiday registered 10 points, six rebounds, five assists and one steal.

The Celtics will remain without Kristaps Porzingis (calf) for Tuesday's game.

Tuesday's game marks the fourth meeting between the teams since the start of the regular season. The Celtics have won two of the first three games.
