There has been a myriad of injury news in the NFL regarding key injuries on the defensive line to several teams. Jonathan Allen and the Washington Redskins got bad news regarding his injury, which is worse than originally expected. Meanwhile, the Seattle Seahawks and San Francisco 49ers also got bad news regarding starting defensive linemen.

Redskins' Allen injury worse than thought

This past Sunday, the Washington Redskins first-round pick Jonathan Allen suffered a lisfranc injury that was expected to keep him out a month. However, he was set to meet with foot specialist Dr.

Robert Anderon to learn the full severity of the injury.

A day after that meeting, a source told ESPN's John Keim that Allen will miss the rest of his rookie season. He has been a key player on the team's defense, starting at tackle in the nickel package, helping to drive back offensive lineman and collapse the pocket.

Allen also occasionally played end in their 3-4 base front and even rushed the passer from a standing position. In five games he recorded 10 total tackles and one sack. Second-year player Anthony Lanier II will now fill his role.

49ers lose Armstead for extended period

The San Francisco 49ers lost 2015 first round pick and starting defensive lineman Arik Armstead on Sunday to a broken hand.

A source told NFL Network's Ian Rapoport that he is expected to be out four to six weeks and that it is likely Armstead will need surgery.

He later reported that the team had put Armstead on injured reserve (IR), although he could be designated to return by the 49ers after eight weeks. Last season, he also landed on IR due to a left shoulder injury that required surgery.

This season, Armstead has 16 total tackles, 1.5 sacks, and one pass defended. With defensive end Aaron Lynch also week-to-week with a calf strain, TheNinersWire's Chris Biderman reported that the team signed defensive linemen Tony McDaniel and Leger Douzable.

Seahawks decide to put Avril on IR

During an interview with SiriusXM NFL Radio today, Seattle Seahawks head coach Pete Carroll said that defensive end Cliff Avril was being put on IR.

Avril suffered a neck injury during the team's week four victory over the Indianapolis Colts. Carroll said he is dealing with neck and spine issues from the injury.

He also added that Avril has been meeting with doctors and that he is “seriously looking at a big decision.” Bob Condotta of the Seattle Times pointed out that along with earlier statements there is speculation that Avril's career could be in doubt.
