Koppen leaves game with ankle injury

New England center Dan Koppen has gone to the locker room with a
left ankle injury in the Patriots’ opener at Miami, and he has been
ruled out for the rest of the game.

Koppen rode off in a cart sitting up late in the first half
Monday night after Dolphins linebacker Karlos Dansby fell on his
leg.

Koppen was replaced at center by Dan Connolly.
