Washington Wizards centers Etan Thomas and Brendan Haywood were involved in a physical altercation last Thursday in which the two traded punches at Verizon Center, the Washington Post writes, citing two team sources for the information.

One source, who requested anonymity because the team was trying to keep the incident private, said Thomas was angry over comments made by Haywood's agent, Andy Miller, on Oct. 30.

Miller was critical of Coach Eddie Jordan's decision to select Thomas as the starting center over Haywood, believing Jordan chose Thomas out of personal animosity toward Haywood rather than performance. "My concern is that this is based on personal issues rather than professional ones," Miller said the day of the decision.

Thomas felt that Miller's comments were a slight toward him, he approached Haywood and threw the first punch once the argument escalated, a source said. According to the source, Haywood responded to the punch by body-slamming Thomas to the ground, tearing out at least two of Thomas' dreadlocks in the process. The two players were separated by teammates and the altercation ended.

It is not the first time the two have fought.  Haywood was suspended for one game after he and Thomas got into a fight during practice last season.
