FOXBOROUGH, Mass. — Patriots linebacker Jerod Mayo, whose 546 tackles since 2010 are the most in the NFL, was placed on season-ending injured reserve Wednesday.
After making a tackle Sunday, Mayo reached for the upper right area of his chest. But the team didn't disclose details of the injury, and his agent did not respond to a Yahoo report that Mayo had surgery for a torn chest muscle.
Rookie Jamie Collins and fourth-year player Dane Fletcher are expected to fill in for Mayo.
Meanwhile, receiver Danny Amendola (concussion) and corner Aqib Talib (hip flexor) missed practice. Their status hasn't been determined.
"We've lost some guys, dealt with some issues like every other team," New England quarterback Tom Brady said "We're handling them okay. We're 5-1. It's a decent start."
Manuel out: Bills quarterback EJ Manuel will miss another 4-6 weeks with a sprained right knee. The former Florida State star was hurt Oct. 3. The team said then his return wouldn't be known until after swelling went done and doctors re-examined the knee.
Giants sign Hillis: The Giants signed running back Peyton Hillis, whom the Bucs cut Sept. 21.
Cowboys: Defensive tackle Jay Ratliff, an All-Pro in 2009 elected to the Pro Bowl in four consecutive seasons, was released after failing a physical.
