Chad Henne will be Jacksonville's starting quarterback Sunday against Tennessee.
Coach Mike Mularkey made the announcement Monday, one day after Henne threw for 354 yards and four touchdowns in a 43-37 overtime loss at Houston.
Blaine Gabbert injured his right forearm early in the game and had trouble gripping the ball.
Henne replaced him in the first quarter and completed 16 of 33 passes. He connected with Cecil Shorts III on a 67-yard touchdown and later hooked up with Justin Blackmon for an 81-yard score. He also found tight end Marcedes Lewis for two TDs in the red zone.
Mularkey says Gabbert is questionable against the Titans.
If Gabbert can't play, the Jaguars will promote John Parker Wilson from the practice squad to serve as Henne's backup.
