Patriots center Dan Koppen suffered a left ankle injury late in the first half of Monday night's win against the Dolphins and was carted off the field. While the team didn't release any details on the injury, it's believed to be serious and there have been reports that the ankle in broken. "That's tough. He's the best and there's no one like him," Patriots quarterback Tom Brady said. "I think he and I have a great chemistry between the two of us. We always have and he's one of my great friends. Hopefully he's back at some point. We're certainly going to miss him but at the same time other guys have to step in and do the job. I think that's part of what this game's all about, other guys stepping in when they're called upon and executing just as if he was in there. Hopefully we get him back at some point."
