After logging his first career 17-start season in Miami last year, cornerback Jack Jones is headed elsewhere. The 49ers are signing Jones, Ian Rapoport of NFL Network relays. It will be a one-year pact, per Adam Schefter of ESPN.
A fourth-round pick of the Patriots in 2022, Jones is now joining his fourth organization and returning to his native California. Along with the Pats and Dolphins, Jones has spent time with the Raiders. The 28-year-old has intercepted eight passes over 59 games and 38 starts
Jones began his career with a 13-game, two-start rookie year in which he picked off two passes. However, his run in New England didn’t last much longer. Jones was arrested in June 2023 after trying to bring two loaded firearms on a plane, though charges were later dropped. He then began the season on IR as a hamstring injury. Just five games after the Patriots activated Jones, they waived him amid on-field struggles and more off-field issues. New England quickly cut the cord after Jones missed curfew ahead of a game in Germany.
Jones temporarily found a home in Las Vegas, which claimed him on waivers. The move reunited him with then-Raiders head coach Antonio Pierce, who coached him in high school and at Arizona State. With two pick-sixes and four passes defensed, Jones had a productive seven-game finish to the season. Pierce remained at the helm in 2024, during which Jones recorded his first 17-game season and started 16 times. Jones added another three INTs, but with Pierce out the door, the Raiders released the corner last spring.
Three-plus months after the Raiders cut him, Jones joined the Dolphins in late July. While injuries ravaged the Dolphins’ secondary, Jones had a second straight healthy season and led their corners in defensive snap share (91.5%). The 5-foot-11, 175-pounder tallied 77 tackles, six passes defensed, two forced fumbles and a pick, but Pro Football Focus ranked his play a below-average 62nd among 112 corners.
Now set to play for new 49ers defensive coordinator Raheem Morris, Jones will give the club another experienced choice on the outside. Deommodore Lenoir and Renardo Green, the 49ers’ starters last year, remain atop the depth chart.


He will be singing the theme from “The Love Boat” at all home games.
