Gabbert will start Saturday's preseason contest against the Titans, Joey Knight of the Tampa Bay Times reports.
Gabbert entered last weekend's exhibition matchup against the Bengals after Tom Brady handled a single series, but the journeyman veteran will officially get the start Saturday. After Gabbert, who looks set to reprise his role as Brady's primary backup during the regular season, Ryan Griffin and rookie Kyle Trask also stand to see some action.
