Jacob Cowing Injury: Limited to open week

Cowing (concussion) was a limited participant in Wednesday's practice, Cam Inman of The San Jose Mercury News reports.

Cowing was diagnosed with a concussion during Sunday's 20-17 loss to the Seahawks after taking a hit to the head during a punt return. He'll have to clear the league's five-step concussion protocols in order to suit up against the Packers on Sunday.
