The Patriots may have come away with a big victory during their 38-24 win over the Dolphins Monday night, but they walked away suffering a big loss as they get ready to return to New England.

They saw center Dan Koppen go down with 1:29 left in the half, after he had a player fall on his leg on a quarterback sneak.  He immediately dropped face down to the turf with his fists clenched – and you knew he was obviously hurt.

Koppen was carted off the field after the play, which came on a day where he should have been celebrating is his 32nd birthday.  He was later seen on crutches coming out of the X-Ray room, and then later on the sidelines still on crutches and in a walking boot.

It’s a tough blow to a team that’s already seen two offensive linemen go down recently, with Ryan Wendell and Sebastian Vollmer both sitting out Monday’s game with an injury.  After Koppen left, Dan Connolly moved to center, which ended the rotation they had been using at right guard to spell newcomer Brian Waters.

As expected, the extent of his injury wasn’t revealed – with the team later saying he was “Questionable” to return.  That was somewhat humorous at the time, because it came mere minutes after Koppen was carted off the field.

The 5th Quarter reported immediately after that he suffered a broken left ankle, which likely means he could potentially be gone for the season.
