You know what sounds painful? A bruised lung. It's one thing to bruise your knee or your ankle or your hand. But a bruised lung? Um, ouch.

That's exactly what Browns rookie Barkevious Mingo suffered during Cleveland's preseason game against the Lions last night, though. Although the Browns initially thought Mingo had injured his rib during the game, he was evaluated further afterwards and ended up having to go to the hospital for a bruised lung. He was held overnight for further evaluation.

Is it just us, or does it seem like a lot of guys are getting injured this preseason? We hope it's not a sign of things to come in the regular season. Because we don't know how many more of these freaky injuries teams can take.
