Juan Toscano-Anderson is known for his hustle, and it led to an injury Saturday night during the Warriors' 119-114 loss to the Boston Celtics at TD Garden.
Midway through the fourth quarter, Toscano-Anderson saved a ball that was going out of bounds and crashed over the scorer's table on the sideline, falling hard to the ground.
After the game, the Warriors announced that Toscano-Anderson has been diagnosed with a concussion and will enter the league's concussion protocol.
The play by Toscano-Anderson led to a 3-pointer by Steph Curry, but everyone's attention quickly turned to JTA.
Toscano-Anderson remained on the floor, with computers and chords surrounding him, for a few minutes and was attended to by Warriors' trainers and players before walking to the locker room with a towel over his head.
"That's a competitor," Warriors coach Steve Kerr said after the game. "Juan is a guy, you want that guy on your team."
ABC's Rachel Nichols reported during the broadcast that Toscano-Anderson sustained a laceration on his head and was being evaluated for a possible concussion.
Kerr told reporters after the game that Toscano-Anderson hit his head pretty hard and was getting stitches.
Shortly after the game ended, Toscano-Anderson sent out a tweet reassuring Warriors fans that he was fine.
In 25 minutes off the bench before exiting, Toscano-Anderson had four points, six rebounds, four assists and was a plus-14.
