Jaguars quarterback Blaine Gabbert turned in a sharp performance but suffered a sprained right thumb in Saturday's preseason game against the Jets, according to ESPN.

Gabbert and the first-team offense got four series of work. He connected with Allen Reisner for a 5-yard touchdown pass in the first quarter. He completed 13 of 16 pass attempts for 165 yards and one touchdown with a 130.5 passer rating.

It is unclear when Gabbert suffered the injury. His status remains uncertain for the team's third preseason game against Philadelphia on Aug. 24.
