Oh, yes they do. There have been numerous cases of NFL players playing on broken limbs. They'll play on a broken bone unless the injury makes it impossible for them to play. The most bizarre example I know if is San Francisco 49ers safety Ronnie Lott. He broke a finger in a game and he had his medic cut it off and tape it up and he finished the game with a bandaged hand and a missing finger. I guess technically he was playing without a broken bone since they cut the broken bone off, but, shit, that showed some grit. Emmit Smith of the Dallas Cowboys played one of the NFC Championship games in searing pain with a separated shoulder. Terry Bradshaw of the Pittsburgh Steeler played a game with a broken bone in his foot. Tony Romo of the Cowboys played 4 games last season with broken ribs and a punctured lung. However, an older Cowboys QB can top even that. Don Meredith came out of the hospital to play a game with a broken rib, a punctured lung, and pneumonia, and this was before the flap jacket was invented. He got his nose broken in the game, but played the game through to the end. Yeah, there are some pads in American football and they probably help some. But there ain't no F'n way those guys are weenies. It's a rough, rough sport. Here are some more examples if you're interested: http://bleacherreport.com/articles/8...in-nfl-history
