The Jaguars are not scheduled to practice Tuesday.
Gabbert, who was carted from the practice field Monday with the ankle injury, participated in the team's walk-through later that night. Coach Gus Bradley called the injury a "freak deal."
Veteran guard Uche Nwaneri stepped on Gabbert's ankle while trying to move to pick up a stunting defensive end. Gabbert fell to the ground and then slammed his helmet against the grass in frustration.
Gabbert, a former first-round draft pick, is competing with Chad Henne for the Jaguars' starting quarterback position.
Gabbert played his entire rookie season in 2011 with a nagging toe injury. He missed the final six games last season after injuring his right forearm. He also played through a torn labrum in his non-throwing shoulder.
Before the collision, Gabbert was having one of his better days in camp. Two days after a rough practice that included several botched snaps, Gabbert completed 11 of 15 passes in 11-on-11 drills Monday.
