The Celtics lost the game and may have lost Rajon Rondo for a few more after a fight broke out during the second quarter of Brooklyn’s 95-83 win Wednesday night at TD Garden.

The Nets used a 38-12 run over a 13-minute span in the first and second quarters to take a 47-26 lead with 3:49 remaining in the second. With 25.9 seconds to go in the half Kevin Garnett was fouled by Brooklyn’s Kris Humphries. Rondo came to Garnett’s defense, shoving Humphries and setting off a fight that spilled over into the first few rows of the stands. Rondo and Humphries were ejected; Brooklyn’s Gerald Wallace, who already had one technical foul, received a second and was tossed. Garnett received a technical. In addition to losing Rondo, the Celtics had nine turnovers in the second quarter.
