Head coach Mike Vrabel said that Tannehill (ankle) will probably be limited at practice Wednesday, Jim Wyatt of the Titans' official site reports.
Per Wyatt, Tannehill -- who wasn't wearing a walking boot when he spoke to the media Wednesday -- noted that he has a right ankle sprain and is improving as Sunday's game against the Texans approaches. While the veteran signal-caller appears to be trending in the right direction, if Tannehill ends up sitting out this weekend, Malik Willis would be next up for reps.
