The San Francisco 49ers are adding another depth piece to their front seven on Tuesday, as they're signing defensive end Jaylon Allen.

Here we'll try to look at the three San Francisco 49ers players on the roster bubble who must shine in the 2025 NFL preseason.

The San Francisco 49ers have seen some roster turnover in the last few months, but defensive end Nick Bosa is stepping up and looking to lead.

NFL insider Ian Rapoport reported that the 49ers had signed DE Jaylon Allen, who played for the UFL’s Memphis Showboats in 2024.

The Philadelphia Eagles gave up on Bryce Huff after just one season, unable to get the same production out of the defensive end that he showcased during his final year with the New York Jets.

Allen originally was signed as an undrafted free agent by the Denver Broncos last year, but they released him with an injury settlement, and eventually signed with the Memphis Showboats of the UFL, where he played in 10 games, started nine, record two sacks and 27 tackles, according to The Football Database. So, he's a camp body.
