Fizpatrick is getting second opinions to determine severity of the injury, Rivera said, adding that he doesn’t yet know how long he’ll be on IR. Fitzpatrick had an MRI on Monday to see whether he suffered a hip subluxation and to determine the severity of the injury.
Heinicke, a fan favorite after his strong showing in a playoff loss to the Tampa Bay Buccaneers, replaced Fitzpatrick. He finished 11-for-15 for 122 yards and a touchdown.
