Brad Stevens said after Monday night’s win over the Milwaukee Bucks that his side’s first half display was the best offensive performance from his side all season.
Jayson Tatum lit it up in the first two quarters, hitting four of his five three-point attempts.
And Kyrie Irving continued his impressive scoring form, ending the night on 32 points.
But the Celtics will not be at full strength with both Marcus Morris and Jayden Brown unavailabile.
Dallas meanwhile have picked up some good form of late and have a solid record at the TD Gardens – winning six of their last eight games in Boston.
