OWINGS MILLS, Md. -- Nose tackle Michael Pierce is undergoing arm surgery Thursday, becoming the fourth Ravens player to suffer a season-ending injury in the first three weeks of the season. A source confirmed that Pierce made the decision to have surgery Wednesday night. Pierce tore his left biceps in the Ravens' 37-26 win over the Patriots. He had been one of the top free-agent additions for Baltimore, signing a three-year, $16.5 million deal in March.
There was a chance that Pierce would choose to play with the injury and have surgery after the season. But Pierce now joins cornerback Kyle Fuller (knee), offensive tackle Ja'Wuan James (Achilles) and outside linebacker Steven Means (Achilles) as Ravens players who are out for the season.
