Pats expect to lose Koppen for a while

According to a source, Patriots center Dan Koppen is scheduled to undergo an MRI today and the expectation is that it will confirm the initial diagnosis Monday night, a broken left ankle that will sideline him for an extended period of time.

The injury wouldn't necessarily be season-ending for Koppen, although it could be a situation where the team has to make a decision on how long it could hold a roster spot for Koppen in the event he could return at some point in the second half of the season. Those team-based decisions are often affected, in part, by other needs on the roster.

For now, the Patriots know Koppen won't be part of their short-term plans. On Monday, six-year veteran Dan Connolly filled in at center when Koppen was injured at the end of the first half, and he is likely to remain there this week as the team prepares to face the Chargers on Sunday at Gillette Stadium. The health of reserve Ryan Wendell, who didn't make the trip to Miami because of a calf injury, also figures to be a factor in the team's decision-making process.
