Dennis (ankle) underwent an MRI after the Buccaneers' Week 4 loss to the Packers, Jenna Laine of ESPN.com reported Monday.
Analysis:Dennis exited the loss to the Packers early with an ankle injury after entering the contest already nursing a calf issue. The fact he required an MRI does not seem to bode well for the 26-year-old's near-term outlook. For the time being, it remains unclear how significant Dennis' injury is and how much time he may be required to miss.
