Ulumoo Ale was looking like one of the biggest storylines early in Washington’s first fall camp under Kalen DeBoer.

A converted offensive lineman, Ale was reportedly working with the first-team defense as an interior lineman. But the 6-foot-6, 333-pound junior was carted off the practice field on Wednesday after suffering an apparent left knee injury. The Seattle Times’ Mike Vorel reported that Ale was placed in an air cast before leaving the field.

Per Vorel, DeBoer wasn’t available after practice to comment on the severity of the injury.

But just last week the head coach told reporters he felt the converted lineman could make an immediate impact on the Husky defense in 2022. Ale started 10 games over the last two seasons as a guard for UW. Among guards to see at least 250 snaps last season, Ale allowed the fifth-fewest quarterback pressures in the Pac-12 (per PFF). Despite the size, he showed an ability to get out and pull and block in space.

After slimming down this offseason, he was looking like a potential plug in the middle of what was a leaky run defense last season.

The injury leaves UW with a bit of a depth concern up front along the defensive line. Healthy scholarship bodies include Tuli Letuligasenoa, Kuao Peihopa, Jacob Bandes, Voi Tunuufi, Siaosi Finau, and Jayvon Parker. Per Vorel, Faatui Tuitele has been limited in camp so far with an undisclosed injury and Armon Parker is expected to miss the entirety of fall camp.
