Mac Jones quietly is having an outstanding training camp. Through five practices, he has completed a whopping 77 percent of his throws and been intercepted just once.

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 held their first padded practice of training camp on Monday, and they have three young players standing out so far.

Early indications are Pinnock, 26, will step in as a starting safety when the 49ers open the regular season on Sept. 7 in Seattle. With Malik Mustapha sidelined while rehabbing an ACL tear, Pinnock and third-year player Ji’Ayir Brown are running with the first team.

As he enters his first season with the Indianapolis Colts, veteran cornerback Charvarius Ward is willing to admit that he didn't put his best foot forward during the 2024 campaign.

The 49ers are adding another defensive lineman to the mix. Per Ian Rapoport of NFL Media, San Francisco is signing defensive end Jaylon Allen. Allen spent time with the Broncos last year but then played the 2025 UFL season with the Memphis Showboats. He appeared in 10 games, tallying 23 tackles, 1.5 sacks, and a forced fumble.

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.

San Francisco 49ers defensive end Nick Bosa entered at No. 57 after another Pro Bowl campaign. Houston Texans running back Joe Mixon cracked the list at No. 58 following his Pro Bowl season in 2024. Here's where the list stands after Tuesday's addition.

Rookie C.J. West dominated at the onset of the 49ers’ first full-padded practice Monday, a positive sign for an overhauled defensive front.
