The Washington Redskins have signed veteran quarterback Josh Johnson to back up new starter Mark Sanchez, John Keim of ESPN reports.

The Redskins lost yet another starting quarterback on Monday night as Colt McCoy suffered a season-ending injury when he fractured his fibula in the first quarter of their 28-13 loss to the Philadelphia Eagles.

McCoy was making his second start of the season after replacing starting QB Alex Smith, who broke both his tibia and fibula in a loss to the Houston Texans on Nov. 18.

The Redskins also worked out free-agent quarterback Landry Jones and Ryan Mallett today but opted to sign Johnson, who is familiar with Redskins head coach Jay Gruden’s system.

Johnson and Gruden were together previously in two teams: the Tampa Bay Buccaneers in 2008 and the Cincinnati Bengals in 2013. Gruden was an offensive assistant with the Bucs and the Bengals offensive coordinator.

Johnson was originally drafted by the Buccaneers in the fifth round of the 2008 NFL Draft. He played 26 games in three seasons with the Bucs, completing 54 percent of his passes for 1,042 yards with five touchdowns and 10 interceptions.

He appeared in three more games in the next two seasons, which he spent with the Cleveland Browns and the Bengals.

Since then, Johnson has landed on a number of different teams — the 49ers, Jets, Colts, Bills, Ravens, Giants, Texans and Raiders — but never played a down of football in any one of those stops.

But if the Redskins’ unbelievably bad luck with quarterback continues, there’s a chance Johnson could finally see snaps for the first time in a long time.
