The 49ers on Tuesday officially announced the placement of punter Mitch Wishnowsky on the non-football injury list. They also announced the addition of cornerback Terrance Mitchell to their 90-man roster.
Wishnowsky is dealing with a back injury according to general manager John Lynch. The 31-year-old punter suffered the injury while lifting weights away from the team facility. He won’t count against a roster spot while he’s on the NFI, and the team can activate him any time. Lynch said the club isn’t concerned about a long-term back issue for their punter and won’t be adding a replacement to their offseason roster.
