The San Francisco 49ers signed former UFL edge rusher Jaylon Allen on Tuesday.

Allen, 25, originally joined the Denver Broncos as a 2024 undrafted free agent but was later waived with an injury settlement.

Allen worked out with the 49ers last weekend following a similar tryout with the Arizona Cardinals, per reports.

He tallied 23 tackles, 21 quarterback pressures and 1.5 sacks in 10 games for the Memphis Showboats in 2025.

The 6-foot-2, 245-pound defensive end played college football at Memphis from 2019-23, recording 13 sacks, three fumble recoveries and 150 tackles in 60 games.

The 49ers also placed defensive lineman Tarron Jackson on injured reserve.

Jackson, 27, was a sixth-round pick by Philadelphia in 2021 and has 18 tackles in 24 games with the Eagles (2021-22) and Carolina Panthers (2024).
