Triple-A Durham activated Driscoll (ankle) from its 7-day injured list Friday and assigned him to Single-A Charleston.
Driscoll, who opened the year on the injured list, completed a rehab assignment with the Florida Complex League Rays and then Charleston before being reinstated. The 28-year-old catcher is under a minor-league contract with Tampa Bay and has made seven appearances for the Single-A club overall, batting .231 with three extra-base hits, five RBI and one walk across 28 plate appearances.
