Jonathan Allen was anticipating playing with two more former Alabama teammates on the Washington Redskins’ defense in the 2019 season.

After Washington's first Phase III practice of its offseason program on Monday, it appears he'll get to play with only one more.

Reuben Foster suffered a knee injury on Monday, and reports indicated the linebacker won’t make his Redskins’ debut in 2019 after suffering a torn ACL in his left knee.

Even before knowing the extent of Foster's injury, Allen said he knew his four-year Crimson Tide teammate would make a full recovery.

“Trust me: Reuben’s going to be fine,” Allen said after Monday’s practice. “… He’s going to work his ass off to recover and get back and help this team. He just wants to win.”

Safety Landon Collins didn’t participate in team drills on Monday as he recovers from a shoulder injury that caused him to miss the final four games of the 2018 season with the New York Giants. The three-time Pro Bowler joined Washington in March for a six-year, $84 million contract.

“He’s an alpha male,” Allen said of Collins. “He’s a guy who’s going to do it right and do it physical. I love the way he comes up and plays inside the box. He’s able to reach across the field and make plays all over. He’s an all-around safety, and I’m glad he’s on our team.”

Allen joined the Redskins as the 17th player picked in the 2017 NFL Draft. In the 2018 draft, Washington used the 13th pick on Alabama’s Da’Ron Payne and installed him at nose tackle between Allen and Matt Ioannidis on the defensive line. With top backups, Tim Settle and Caleb Brantley returning, too, Allen said he feels good about the Redskins’ defensive line.

“We like everybody we have in this room,” Allen said. "Everybody in this room is willing to work, they can do what we ask them to do and they can play football. That’s really all I can ask for. …

"When you have a group of guys that will hold you accountable, it really pushes you to be the best every day. The thing we always say is: You should never feel comfortable. Never. You should never feel comfortable, so we try to make everything and everybody uncomfortable in this building. That's just our goal every day is to make it as uncomfortable as possible for everybody to help promote growth."

And how do the defensive linemen make it uncomfortable?

“Talk (expletive) and compete,” Allen said.

Among the NFL's 32 teams during the 2018 season, Washington finished 15th in scoring defense, 17th in total defense (based on yards given up), 15th in passing defense and 17th in rushing defense. The Redskins had the NFL's worst rushing defense in 2017, when they finished 27th in scoring defense and 21st in total defense.

“We feel like when we’re consistent and we do our job, we can play with the best of them,” Allen said of the Washington defense. “But that’s the tough part in the NFL is doing it week in and week out, so as long as we can do that, we’ll be fine, and that’s our goal every day -- just get consistently better in what we do.”

The Redskins have Mason Foster returning at one inside-linebacker spot. With Foster out, another former Alabama standout could step into the starting lineup. Shaun Dion Hamilton started the final four games of his rookie season in 2018.

“Every team deals with injuries,” Allen said. “We just have to deal with them the best we can and move on.”
