The Washington Redskins placed Ryan Kerrigan on injured reserve Friday, ending the most challenging season of the linebacker’s career.

Kerrigan suffered a calf injury during the Redskins’ 20-15 loss to the Green Bay Packers on Sunday and did not practice at all this week. This will be the first time Kerrigan has been on IR; he held the team’s ironman streak of 139 consecutive games played before a concussion forced him to miss Week 13 against the Carolina Panthers. That was the first game Kerrigan had missed in his nine-year career, and now he will miss the season’s final three.

“He’s a consummate pro in every respect,” interim coach Bill Callahan said. “I know that he didn’t want to finish this season in this fashion, but it’s in the best interest of his health, obviously, to go this route right now.”

The 2019 season can now officially be called the worst of Kerrigan’s career. In 12 games, he finished with a career-low 25 tackles and a career-worst 5½ sacks, falling below the 7½ he posted as a rookie in 2011. The four-time Pro Bowl pick is one sack shy of matching Dexter Manley’s franchise record of 91.

On Sunday against Philadelphia, Ryan Anderson is expected to start in Kerrigan’s absence opposite rookie Montez Sweat. Nate Orchard will get more opportunities; he shined when Kerrigan was out against the Panthers.

Callahan also announced that wide receivers Paul Richardson Jr. (hamstring) and Trey Quinn (concussion) are out Sunday. Cornerbacks Quinton Dunbar (hamstring), Fabian Moreau (hamstring) and Josh Norman (illness); guard Brandon Scherff (elbow/shoulder); and safety Montae Nicholson (ankle) are questionable. The Redskins signed tight end Caleb Wilson off the Arizona Cardinals’ practice squad to fill Kerrigan’s roster spot.

For the Eagles, tackle Lane Johnson (ankle) is out, and wide receiver Nelson Agholor (knee), defensive end Derek Barnett (ankle), running back Jordan Howard (shoulder) and cornerback Ronald Darby (hip flexor) are questionable.
