PITTSBURGH -- The Steelers signed a trio of XFL products on Wednesday, supplementing their free-agency signings with two members of the New York Guardians -- including the league's sacks leader -- and one alum of the DC Defenders.

The Steelers agreed to contracts with defensive tackle Cavon Walker, offensive tackle Jarron Jones and safety Tyree Kinnel. The positions filled are ones of need for the Steelers, who lost depth at all three spots during free agency with the departures of defensive tackle Javon Hargrave, offensive linemen Ramon Foster and B.J. Finney, and safety Sean Davis.

The Steelers have been open in the past to signing players from alternative football leagues, signing safety Kameron Kelly from the Alliance of American Football prior to last season. Kelly started one game for the Steelers but was released after he was arrested at a local bar late in the season.

In an interview with local beat writers in February, Steelers general manager Kevin Colbert said the team would be monitoring and evaluating the XFL for talent.

"The XFL has taken some of the guys we would have signed as futures [contracts]," Colbert said prior to the NFL scouting combine. "We'll have to do more work on undrafted guys because of that. Traditionally, we sign about 15, but we might have to sign 20-22."

"We got an initial feel for that group, and we'll continue to monitor those teams throughout the season."

Though the XFL season was shortened due to COVID-19, the Steelers saw enough to merit signing the trio of players.

Listed at 6-foot-2, 284 pounds, Walker led the XFL with 4.5 sacks and nine quarterback hits as a member of Guardians. The Maryland product went undrafted in 2018, but spent preseasons with the Bears and the Chiefs. Walker became the second defensive lineman added by the Steelers in free agency, joining former Baltimore DL Chris Wormley, who arrived in Pittsburgh via trade.

Jones, a Notre Dame product, spent training camp or preseason with the Bills, Cowboys, Giants and Seahawks, but couldn't stick with any of them. He converted from defensive line to offensive line upon joining the Giants, and the much-needed reps as the Guardians' left tackle should allow the the 6-6, 320-pound offensive tackle to compete for a roster spot in Pittsburgh.

Kinnel was the final signing of the group after his stint with the Defenders. Kinnel had 17 total tackles in the shortened season. After a Michigan career during which he had 170 tackles, two interceptions and one sack, Kinnel signed with the Bengals as a undrafted free agent in 2019 but was cut after training camp.
