The injury count continues to rise for the Ravens this summer. 

Last week the offensive line was hit hard and barely had enough players left to finish the game. The injury bug flipped over to the defensive line Saturday night against the Washington Redskins.

The Ravens had three defensive linemen leave early, including starting defensive tackle Timmy Jernigan. The second-year defender suffered a knee injury and the team didn't give an update on his status after the game.

"We'll have to learn more about that in the next day or two," Head Coach John Harbaugh said. 

Reserve defensive linemen Lawrence Guy (knee) and DeAngelo Tyson (shoulder) also went down and didn't return.

"It was tough seeing guys go down, but we don't make excuses," veteran defensive lineman Chris Canty said. "It's next man up. We have confidence in the guys that are in the game, that they will get the job done, and that's how we approach everything."

In addition to losing the three defensive linemen, offensive lineman Ryan Jensen (concussion) and cornerback Chris Greenwood (leg) also got hurt.

The injury to Jernigan is most alarming because he's a critical piece in the middle of the defense. He's tasked with replacing perennial Pro Bowler Haloti Ngata, and the Ravens expect him to be a three-down lineman.

Jernigan has also dealt with injuries throughout his young career, including a knee injury that sidelined him for four games last season. It's unclear if the injury he suffered Saturday is to the same knee.

This year's training camp and preseason have taken a toll on the Ravens, as they've had key players go down on both sides of the ball.

Safety Matt Elam and defensive end Brent Urban both suffered torn biceps that could cost them the entire season. Wide receiver Breshad Perriman (knee) hasn't practiced since July 30 and the team has no timetable for his return.

Wide receiver Michael Campanaro (soft-tissue issue) missed the last two games and cornerback Lardarius Webb (hamstring) has yet to play in the preseason. Rookie tight end Maxx Williams also missed Saturday's game with an undisclosed injury that forced him to wear a non-contact jersey in practice all last week.

Starting left tackle Eugene Monroe (wrist) and left guard Kelechi Osemele (foot) both missed Saturday's game, as well.

The Ravens have two weeks before opening the regular season in Denver, and a top priority is to get healthy before then.

"You're just hoping that the injuries that occurred tonight aren't serious, and that we can get them back," veteran inside linebacker Daryl Smith said. "We need everybody. Hopefully it's not serious."
