Bucs cornerback Richard Sherman suffered a calf injury in pre-game warm-ups at Washington on Sunday and wasn’t able to play in the team’s 29-19 loss. Sherman returned to practice last week after recovering from a hamstring injury in the first series at Philadelphia that caused him to miss the Chicago and New Orleans games. The team was hopeful that he could return to action and start at Washington.

According to Bucs head coach Bruce Arians, the 33-year old Sherman suffered a fairly serious injury to his calf.

“‘Sherm’ strained his calf before the game,” Arians said on Monday, awaiting the results of an MRI. “I doubt seriously if he’ll be back anytime soon.”

On Tuesday night, the results of that MRI were revealed by NFL Network’s Ian Rapoport, who reported that Sherman had suffered a grade 2 calf strain that would cause Sherman to miss several weeks.

Dee Delaney started in place of Sherman on Sunday and struggled, giving up a touchdown in the first half. Delaney also suffered a concussion and is in the protocol, which will likely miss Tampa Bay’s upcoming game against the New York Giants on Monday Night Football at Raymond James Stadium next week.

Arians said that starting cornerback Sean Murphy-Bunting, who has been out since Week 1 when he suffered a dislocated elbow, returned to practice and started using his arm last week. He’s made enough progress that there is a chance he could play on Monday night.
