Arizona TE not yet cleared for Saturday

TUCSON, Ariz. -- Arizona tight end Rob Gronkowski might miss the Wildcats' opener against Central Michigan because of a back injury.

Coach Mike Stoops said Monday that medical staff had yet to clear Gronkowski to play in Saturday's home game.

Stoops said Gronkowski's availability will be "kind of a week-to-week decision."

The 6-foot-6, 265-pound Gronkowski, a junior who was first-team All-Pac-10 last year, has 75 career catches for 1,197 yards and 16 touchdowns.
