49ers roster moves: Practice window opened for RB Trenton Cannon

The #49ers made a few roster moves, one of which was opening RB Trenton Cannon’s practice window.

The 49ers on Wednesday announced a handful of roster moves which included some very good news on running back Trenton Cannon.

Cannon, who was taken off the field in an ambulance because of a hit to the head and neck area on the opening kickoff in Week 13, had his practice window opened after a five-week stint on injured reserve. The 27-year-old avoided any additional neck or head injuries beyond his concussion. Now he has a chance to return and contribute for San Francisco in the postseason.

The other moves were all on the practice squad.

Safety Doug Middleton was reinstated after a stint on the practice squad IR and quarterback Tyler Bray was released.

The 49ers also added punter Ryan Winslow with Mitch Wishnowsky in concussion protocol. Winslow has seen action in four games with three different teams this season. He kicked for two games in Carolina, and one each in Arizona and Washington. In four games he booted 16 punts with an average of 39.1 yards per kick. He also handled kickoffs for the Panthers and Cardinals – a job Wishnowsky typically holds.
