The Mavericks won't know about Brendan Haywood's availability for Game 4 until Tuesday. He was scheduled to go for a second MRI on Monday afternoon and will find out more about his right hip flexor strain. "It feels a lot better than yesterday, but I don't want to commit to anything,'' Haywood said after the Mavericks' practice. "I was able to move at a little better clip, so we'll see how it feels. I've done some jogging, but not any full-out sprints.'' Haywood had an MRI on Friday and is hoping that the second exam will show improvement to the injury he suffered in the second half of Game 2. He missed Sunday's Game 3 and is questionable for Game 4. Haywood said the biggest problems he has are with full-speed moves.
