Eagles' Darby carted off with ankle injury

Philadelphia Eagles corner Ronald Darby was carted to the locker room with a right ankle injury in the second quarter of Sunday's game against the Washington Redskins and will not return, the team announced.

Darby was acquired from the Buffalo Bills via trade for Jordan Matthews.

If Darby is lost for any significant time, it would be a huge blow to the Eagles' secondary, which was already thin going into the season.
