Rob Gronkowski's status for Thursday night's game against the Colts appears to be up in the air.
Gronkowski was not spotted on the practice field this afternoon.
The tight end is dealing with an ankle injury. He was limited in practice leading up to Week 4. He would leave that game in the third quarter and would not return. The Pats, of course, play the Thursday night game, so Gronk's status should at least be a concern for owners. Reports say Gronk's injury is not serious, however.
