ASHBURN, Va. -- The Washington Commanders activated tight end Logan Thomas off the physically unable to perform list Monday, giving them back a crucial part of their offense as the regular season approaches.

Thomas tore his left ACL and MCL last season in a Dec. 5 loss to the Las Vegas Raiders. There was some hope before training camp that he wouldn't have to be placed on the PUP list because of how well his offseason had gone, but those hopes were dashed.

In 22 games with Washington, Thomas has caught a combined 90 passes for 866 yards and nine touchdowns. At the time of his injury, Thomas led the NFL with 144 receiving yards in the red zone during his time with Washington -- despite having missed five games earlier that season with a hamstring injury.

With a new quarterback in Carson Wentz, it's helpful for Thomas to get some work with him on the field before the regular-season opener vs. Jacksonville on Sept. 11.

Washington's tight end depth has been severely tested during camp. Not only was Thomas missing, but No. 2 tight end John Bates has missed most of training camp with a left calf injury and rookie fifth-round pick Cole Turner hasn't practiced since hurting his left hamstring on Aug. 5. Two other tight ends, Alex Armah and Sammis Reyes, were placed on injured reserve last week; Armah was released Monday.

On Saturday vs. Kansas City, Washington only had two tight ends available: undrafted rookie Armani Rogers, a converted quarterback, and Eli Wolf, who was placed on injured reserve Monday with an undisclosed injury.

The Commanders signed tight end Jake Hausmann and claimed tight end Kendall Blanton off waivers from the Los Angeles Rams on Monday.
