According to a report from the NFL Network's Albert Breer, New England Patriots center Dan Koppen is expected to miss between six and ten weeks with what is being called "a severe ankle sprain". The news is considered positive as the initial reports were that he had broken the ankle and would likely be lost for the season.
Koppen suffered the injury during the second quarter of last nights 38-24 win over the Miami Dolphins. Koppen was rolled up on from behind by Dolphins linebacker Karlos Dansby and had his leg trapped underneath him.
The time frame for the injury leaves open the possibility that the Patriots would put Koppen on IR, effectively ending his season, in order to open up a roster spot for so that the team could find a replacement.
The team is already short handed on the line thanks to an injury to Sebastian Vollmer. As a result, free agent signee Brian Waters saw extensive action during the game despite only having been with the team for eight days.
Koppen is in his ninth year out of Boston College.
