The 6-foot-6, 265-pound Gronkowski missed all of last season after back surgery. He said Friday that he received clearance from the surgeon who performed a microdiscectomy on his back on Sept. 24.
Drew Rosenhaus will represent him.
The 20-year-old Gronkowski caught 75 passes for 1,197 yards and 16 touchdowns in 23 games over two seasons, and holds a dozen school single-season and career records for tight ends.
