There's reportedly even a glimmer of hope that Watt could play in Week 17.
Watt suffered the injury in October and was expected to miss the rest of the season, but the Texans are reserving their final IR-return spot for Watt, Rapoport adds.
The three-time Defensive Player of the Year has progressed in his recovery and will undergo an MRI in a few weeks.
Watt was never officially ruled out for the year, but he tweeted after picking up the injury in Week 8 that he was "absolutely gutted" that he wouldn't "be able to finish the season with my guys."
The Texans currently lead the AFC South with a 7-4 record and face the 10-1 New England Patriots in an important AFC matchup Sunday.
