BEREA, Ohio -- Browns quarterback Robert Griffin III broke a bone in his left shoulder and will miss at least eight games.
Griffin was injured on an 11-yard run in the fourth quarter of Sunday's 29-10 loss to the Philadelphia Eagles. As he tried to get out of bounds, Griffin was drilled by Eagles defensive back Jalen Mills.
The team said Griffin will be placed on injured reserve -- under new rules he can brought off the list -- and will be evaluated in 3 to 4 weeks.
The 26-year-old returned to the game for Cleveland's final series, but only handed the ball off while favoring his left arm. RG3 is the 25th quarterback to start for the Browns since 1999, a roll call of rookies, veterans and free agents.
With Griffin out, Josh McCown will start this week's home opener against Baltimore.
Panthers: Rivera: Cam Newton's head is fine
CHARLOTTE, N.C. -- Panthers coach Ron Rivera says Cam Newton's body is sore but his head is fine, and he fully expects the league's reigning MVP to play Sunday against the San Francisco 49ers.
Rivera says "he's resilient and he's moving around pretty good."
Newton took at least four helmet-to-helmet hits in Carolina's 21-20 loss to the Denver Broncos on Thursday night.
The NFL and the Players Association are both looking into whether more should have been done when Newton took a shot to the head in the final minute of the game. Newton was cleared to return and finished the game, getting the Panthers into field goal range, although Graham Gano missed from 50 yards out.
Rivera says he has full confidence that the Panthers medical staff handled the situation properly (see full story).
Seahawks: Russell Wilson has ankle sprain
RENTON, Wash. -- Seattle Seahawks coach Pete Carroll believes quarterback Russell Wilson will be able to play in Week 2 against Los Angeles despite suffering a sprained ankle in the opener against Miami.
Speaking on his weekly radio show on KIRO-AM on Monday, Carroll said Wilson has been diagnosed with a sprained ankle. Carroll said both X-rays and an MRI came back clear, but there is some swelling.
Wilson may be limited in practice this week ahead of facing the Rams, Carroll said.
Wilson has not missed a game during his career.
Wilson was injured in the third quarter of Sunday's 12-10 win over the Dolphins while being sacked by Ndamukong Suh. Wilson had his ankle re-taped and did not miss a snap.
