DALLAS -- Mavs center Brendan Haywood is hurt again.
Haywood headed to the locker room after spraining his right knee during the third quarter of Thursday's game against the Bobcats. Haywood will not return to the game, but the Mavs are describing the sprain as "mild."
Haywood injured his left ankle on the first possession of the March 5 loss to the Oklahoma City Thunder. He missed the remainder of that game and the next four, returning for Tuesday's win over the Washington Wizards.
Haywood is averaging 5.6 points, 6.7 rebounds and 1.1 blocks per game and is the backbone of a defense that has slipped to ninth in the NBA in points allowed. He had six points, eight rebounds and two blocks in 15 minutes against the Bobcats.
