A fight erupted under the Celtics basket with 29.5 seconds remaining in the second quarter of Wednesday night’s game against the Nets, leading to the ejection of three players, including Rajon Rondo.

Kevin Garnett took a hard foul from Brooklyn’s Kris Humphries, which Garnett took exception to. Rajon Rondo came to Garnett’s defense and began to shove Humphries, prompting pushing and shoving from both teams.

Rondo appeared to throw punches toward Lopez. It took about a minute for the players to clear as security staff from all parts of the Garden ran from the tunnel onto the floor. The scrum spread to the first rows of the crowd.

After officials reviewed the play, the following fouls were assessed:

-- Humphries: One personal, two technicals, ejection

-- Gerald Wallace: One technical (his second of the game, leading to ejection)

-- Garnett: One technical

-- Rondo: Ejection

At the time of the ejection, Rondo had three assists, so his streak of double digits ends at 37 games. The Celtics trailed at the half, 51-38. Courtney Lee replaced Rondo in the lineup.
