Brendan Haywood is a game-time decision

The Dallas Mavericks still don't know if Brendan Haywood will play in tonight's Game 3 of the NBA Finals. The 7-foot backup center will be a game-time decision with a right hip flexor injury that he sustained in the fourth quarter of Game 2, coach Rick Carlisle said Sunday morning.

His participation in Saturday's practice was limited to spot shooting and free throws. He spent the rest of the session doing conditioning work in a pool and on an exercise bike.

"Still feeling a little tight," Haywood said as he went to get treatment during Sunday morning's shootaround.

Haywood's value this postseason is not reflected by his statistics -- 4.3 points, 3.3 rebounds in 16.0 minutes a game. He has been a steady defensive presence in the paint with the Mavs' second unit and especially valuable when starting center Tyson Chandler has dealt with foul trouble.

If Haywood is not available to go against the Miami Heat in this pivotal game, 24-year-old Ian Mahinmi might get his first significant minutes of the postseason. The Mavs' other option when starting big man Tyson Chandler rests is to use a smaller lineup with Shawn Marion as an undersized center with Dirk Nowitzki at power forward.
