The Redskins will start quarterback Josh Johnson in Week 15 against the Jaguars after Mark Sanchez was benched in the second half of Sunday's 40-16 loss to the Giants.

Coach Jay Gruden told reporters that Washington will get Johnson ready this week.

"Mark Sanchez, Josh Johnson — can't say enough about them coming in here on really short notice trying to learn an NFL offense and play on a Sunday with limited reps," Gruden said. "They competed and did the best they could at the end of the day. Weren't quite ready."

Johnson replaced Sanchez while Washington was down 40-0. Sanchez completed just 6-of-14 pass attempts for 38 yards and had a pair of interceptions. He hadn’t thrown a pass since 2011 until Sunday.

Washington ended the first half down 34-0 and the team was met with boos as they headed into the locker room.

The Redskins signed Sanchez and Johnson shortly after starting quarterback Alex Smith and backup Colt McCoy went down with leg injuries in consecutive weeks.

Smith broke his leg during the team's 23-21 loss to the Texans in Week 11 and has been dealing with complications as he remains in the hospital. It's been reported he could miss the start of the 2019 season.
