Mitchell (knee) was inactive for Tuesday's practice at mandatory minicamp, Jeremy Reisman of SB Nation reports.
The rookie remains unavailable while rehabbing his knee after suffering a torn ACL in his final season at Virginia Tech. Mitchell expected to receive full medical clearance by now and it's unclear if he did so and was merely being held out as a precaution, but he'll likely be ready to go for next month's training camp. He'll operate as a depth option behind T.J. Hockenson at tight end once healthy.
