Tennessee Titans quarterback Ryan Tannehill will “very likely” miss the remainder of the season (including playoffs) after he suffered a right ankle injury last Sunday in the Titans’ 17-14 loss to the Chargers, that may also require surgery.

Tannehill suffered a right ankle injury after a tackle from Los Angeles Chargers linebacker Khalil Mack on a first-quarter scramble in the Titans’ 17-14 road loss to the Bolts. The 34-year-old then went to the blue medical tent before being carted to the locker room. Rookie backup Malik Willis took over temporarily but Tannehill returned with a heavily taped ankle to played the rest of the game.

Tannehill was not present during practice on Wednesday, with Willis as the starting quarterback during the open portion of the Titans’ practice.  Willis started two games for Tannehill after he suffered a sprain of his right ankle on Oct. 23 against the Indianapolis Colts, before the veteran QB returned to the lineup.

NFL Network’s Ian Rapoport reports that Tannehill was “seriously in doubt” to start Saturday against the Houston Texans. Tennessee heads to Houston game on a four-game losing streak. Tennessee closes the regular season with a Dec. 29 home game against the Cowboys before ending the year with a Jan. 8 road game at Jacksonville in a game that could determine the AFC South winner.
