Backup center James Donaldson was suspended by the Dallas Mavericks for last night's game against the San Antonio Spurs after a practice scuffle that slightly injured one player.

On Tuesday, Donaldson skirmished with guard Rolando Blackman. Guard Derek Harper was scratched twice under an (( eye trying to break up the scuffle.

Dallas has lost 13 of 14, and Donaldson said the losing created tension. Harper disagreed.

"This has nothing to do with what's going on out on the floor," he said. "James is just a 7-foot punk."
