RENTON Richard Sherman is officially out for the season. C.J. Prosise has joined him.
The Seahawks also made official on Tuesday that they’ve indeed brought back veteran cornerback Byron Maxwell, their starter in 2013 and ‘14, on a one-year contract.
The team also signed running back Mike Davis off the practice squad.
Sherman is having surgery this week to repair the ruptured Achilles tendon he got in Thursday’s win at Arizona. The recovery time is about six months for a return to full activity, according to the American Orthopaedic Foot & Ankle Society.
