The Philadelphia Eagles have bolstered their defense with the signing of Ryan Kerrigan.

Defensive end Kerrigan has spent 10 seasons with the Washington Football Team after being picked in the first round of the 2011 draft.

A four-time Pro Bowler, Kerrigan holds the Washington franchise record for sacks with 95.5, which are the fifth-most in the NFL since 2011.

"I'll never be able to sum up what these past 10 years have meant to me in an Instagram post, but what I can say is that they have been some of the best of my life," Kerrigan wrote in a farewell message to Washington on Instagram. 

"I hope you had as much fun watching me as I did playing for you. Thank you, Washington, for everything."

In a subsequent post announcing his signing with Washington's NFC East rivals the Eagles, he wrote: "I know I probably wasn't your favourite player over the past decade, but @philadelphiaeagles fans I'm fired up to be playing for you guys now!"

He joins a Philadelphia defense that was seventh in the NFL in forcing negative passing plays in 2020 with 53 for minus 349 yards.

The Eagles are not short on talented pass rushers. Brandon Graham was fifth in the league among edge rushers last season with a pressure rate of 23.5 per cent, while Josh Sweat's adjusted sack rate of 4.4 per cent was marginally better than that of Kerrigan (4.3) in 2020.

Interior defensive lineman Fletcher Cox had 6.5 sacks and has at least 5.5 sacks in five of his past six seasons.

The Eagles will hope the addition of Kerrigan to an already talented defensive front will help them bounce back from a 4-11-1 season under new head coach Nick Sirianni.
