Gabbert spent last season with the Buccaneers but was placed on injured reserve early in the year because of a dislocated shoulder. Ryan Griffin, who is still on Tampa Bay's roster, served as Jameis Winston's backup in 2019.
The Jacksonville Jaguars selected Gabbert with the No. 10 overall pick in the 2011 NFL Draft out of Missouri. He spent three lackluster seasons in Jacksonville before being traded to the San Francisco 49ers in March 2014.
In 56 career games (48 starts) with the Jaguars, 49ers, Cardinals and Titans, Gabbert has completed 56.2 percent of his passes for 9,063 yards, 48 touchdowns and 47 interceptions.
