Sean McDermott's long tenure in Philadelphia has come to an end.
The Eagles confirmed an earlier report by ESPN's Chris Mortensen that they have fired McDermott, their defensive coordinator. McDermott had spent 12 seasons with the Eagles and was promoted to defensive coordinator in 2009 after the death of longtime defensive guru Jim Johnson.
This season, the Eagles finished 12th in the league in total defense and tied for 21st in points allowed, but they had to deal with a host of injuries, with DE Brandon Graham, FS Nate Allen and MLB Stewart Bradley all seeing their seasons end prematurely. Nevertheless, the Eagles allowed a franchise-high 31 touchdown passes and had the league's worst red-zone defense, with 76.74 percent of opponents' trips inside the 20 resulting in touchdowns.
Despite those shortcomings, the defense forced 34 turnovers, fifth-most in the league, and their 23 interceptions ranked third. The Eagles were one of only two teams that had rookies contributing at least five sacks and five interceptions.
Head coach Andy Reid had said last week that McDermott would remain in Philadelphia.
The Eagles fell to the Packers 21-16 in the wild-card round of the NFL playoffs.
