Love collided with Boston’s Jayson Tatum early in Game 6 and missed the remainder of the contest.
The collision happened with 7:07 left in the first quarter as Tatum tried to get through a screen. Love fell to the ground, and the Cavs intentionally fouled to stop the game at 6:58.
Love went to the bench, sat down and then went to the locker room with a Cavs trainer. Jeff Green replaced Love in the lineup.
Cleveland general manager Koby Altman also went to the locker room to check on Love, who was sidelined with a concussion during the 2016 NBA Finals and late this season.
Despite not having Love, the Cavs played well enough to save their season. LeBron James had 46 points, 11 rebounds and nine assists.
