New England Patriots tight end Rob Gronkowski's back injury is not believed to be serious or a long-term issue, NFL Network's Ian Rapoport reports.
Gronkowski will miss Sunday's Week 7 game against the Chicago Bears after locking up his back during Friday's practice.
The star pass-catcher has been in his usual All-Pro form this season with 26 catches for 405 yards, though he's found the end zone just once.
