Eagles starting cornerback Ronald Darby was forced to leave the game during Philadelphia's ugly loss to the Cowboys on Sunday night after injuring his knee.That injury is a torn ACL.

Eagles head coach Doug Pedeson announced today during his day-after press conference that Darby would miss the rest of the season, and could be the end of his Eagles carer.  He is a free agent at the end of the season.

Darby's injury was a non-contact injury, he was seen in pain while holding his knee then eventually walked off the field to the blue medical tent to be tended to by the team's training staff.

Today, coach Pederson confirmed that it was an ACL tear, ending his season, and possibly his Eagles career.

Darby, Buffalo’s second-round pick in 2015, has one interception and 12 pass breakups this season, Last season he had three picks in eight games, after missing half the season with an injured ankle.

Its another significant loss for the Eagles and might be the final nail in the coffin to their season.  The team has already played without safety Rodney McLeod for most of the season, Sidney Jones and Jalen Mills also sat out the Cowboys game and Chandon Sullivan replaced Darby at cornerback.
