FILE - In this Nov. 19, 2004, file photo, Indiana Pacers' Ron Artest, now know as Metta World Peace is restrained by teammate Austin Croshere and Pacers' assistant coach Mike Brown before being escorted off the court following their fight with the Detroit Pistons and fans in Auburn Hills, Mich. NBA commissioner David Stern suspended Artest for the remainder of this season, and disciplined eight other members of the Pacers and Pistons, sending a strong message that the league won't tolerate the type of unprecedented violence displayed that night. The brawl was speculated to stand among the worst in league history.  (AP Photo/Duane Burleson, File) ORG XMIT: NY153
