J.J. Watt's status for the first two weeks of the regular season with the Houston Texans remains uncertain.
Watt has been on the physically able to perform list since July 25, after he had surgery on a herniated disk in his back.
Bill O'Brien said he is encouraged by Watt's recovery and that "everything is going in the right direction."
"I don't think we can predict whether he'll be ready for Week 1 or Week 2, but he's going to be ready sooner rather than later," O'Brien said.
Watt was originally expected to miss 6-10 weeks after the surgery.
Watt has never missed a regular season game in his five NFL seasons.
