Ashtyn Davis: Everything you need to know

The 49ers signed Davis on Tuesday. Davis is coming off a solid season in Miami, where he recorded a career-high 65 tackles (43 solo) across 15 games. The 29-year-old had spent his entire five-year career with the Jets before signing with the Dolphins in 2025 and will look to earn a spot on San Francisco's final roster for the upcoming campaign.

Davis tallied 65 tackles (43 solo) across 15 regular-season games with the Dolphins in 2025. He also had four passes defensed, including one interception, and one forced fumble. Davis played out the 2025 campaign on a one-year, $1.22 million contract with Miami, setting him up to become an unrestricted free agent this offseason. The 29-year-old safety was relatively unreliable in coverage despite handling an every-down role when healthy for the Dolphins in 2025, making it likely that he'll have to compete during the offseason in order to secure a sizeable workload again for 2026.

Davis posted seven tackles (five solo) and two pass defenses (one interception) during the Dolphins' 20-17 win over the Buccaneers on Sunday. It took until Week 17 of the 2025 season, but Davis finally recorded his first interception of the year after picking off Baker Mayfield midway through the fourth quarter. Davis tied a season high with seven tackles, and the 2020 third-rounder has logged at least six stops in six of his last eight games. He's up to 60 combined tackles through 14 regular-season games, and this Sunday against the Patriots presents his final opportunity to surpass his career-high tackling mark from the 2021 campaign as a member of the Jets (62 combined tackles across 13 regular-season games).
