BEREA, Ohio — Robert Griffin III's comeback cracked.Cleveland's quarterback curse strikes again.Griffin broke a bone in his left shoulder during the fourth quarter of Sunday's 29-10 loss to the Eagles in Philadelphia and will miss at least eight games — and potentially the season — with an injury that leaves the Browns' muddled quarterback situation as jumbled as ever.Cleveland's 25th starting quarterback since the franchise rejoined the league in 1999, Griffin got hurt while trying to run out of bounds. Griffin was near the sideline when by Eagles rookie defensive back Jalen Mills hit him."It's football and these things happen," Browns first-year coach Hue Jackson said. "It's unfortunate but it does happen in this sport."But it seems to happen at an inordinate rate to the Browns, who have had no stability at the game's most important position for nearly two decades.Griffin stayed in the game, but an MRI on Monday revealed that he broke the coracoid bone in his shoulder. He signed with the Browns as a free agent in March in hopes of reviving a career that fizzled in Washington, in large part because of injuries.He does not need surgery at this time and will be evaluated in 3 to 4 weeks. The Browns put Griffin on injured reserve — under new rules he can brought off the list — and he could return at some point in 2016.With Griffin out, veteran and former Bucs quarterback Josh McCown will start this week's home opener against Baltimore. Olsen criticizes league: Panthers tight end Greg Olsen, speaking on behalf of Cam Newton after the quarterback took four shots to the head in Thursday's game against the Broncos, said the league can't contradict itself on matters of health and safety. "I don't think you can talk about player safety and then have what unfolded. You can't talk out of both sides of your mouth," Olsen said. "Player safety sounds great. It's a great offseason rallying cry. It sounds awesome. We got zero yards out of any of those hits." Denver had four helmet-to-helmet hits on Newton in the second half. Only one drew a penalty: A collision with safety Darian Stewart that left Newton on the ground for about 30 seconds. The NFL and players' union are investigating how the Panthers and the league's medical team responded to the final hit; Newton stayed in the game and was not checked for a concussion until afterward in the locker room. Olsen said officials need to start protecting Newton the way it does other quarterbacks: "He's treated like a running back. He's not." Titans anthem statement: Three Titans players say they raised their right fists in the air after the national anthem before Sunday's game — a gesture intended, they said, to honor the victims and heroes of the Sept. 11 attacks and to bring attention to the ongoing unequal treatment of African-Americans and other minorities. Pro Bowl defensive lineman Jurrell Casey, cornerback Jason McCourty and linebacker Wesley Woodyard all had hands over their hearts during the anthem, but seconds after it ended they raised their arms in solidarity with protests around the league. The gesture went unnoticed until Monday after a Sports Illustrated photo started circulating. "I don't want it to be taken as something that was us trying to separate people," McCourty said. "It was more trying to bring everyone together in solidarity trying to come up with a situation to better our country." Chargers: Receiver Keenan Allen went on injured reserve, ending his season, with what's believed to be a torn right ACL. Also, No. 3 overall draft pick Joey Bosa was activated. Bosa missed all of training camp in a nasty contract dispute then tweaked a hamstring last week. Seahawks: Quarterback Russell Wilson shed a protective boot and was walking around Monday afternoon after hurting his foot Sunday. Coach Pete Carroll said, "He's practicing on Wednesday. He's planning on playing" in Week 2 against the Rams.
