Jarrett's undisclosed injury is expected to extend into the regular season, Greg Auman of Fox Sports reports.
Specifics about the injury haven't been made clear, but it appears that the issue is serious enough to put Jarrett's status for the season opener in doubt. The second-year wideout has been slated for a depth role in Tampa Bay's wide receiver room. He got into 10 contests as an undrafted rookie last year, catching four of nine targets for 60 yards over 106 offensive snaps.
