49ers Lock In Jack Jones on One-Year Deal, Add Veteran Depth to Secondary
The San Francisco 49ers are beefing up their cornerback room. The team agreed to a one-year contract with free agent CB Jack Jones on Friday after he visited the facility, according to agent Drew Rosenhaus. It's a move that signals the 49ers are serious about shoring up their defensive backfield before the regular season ramps up.
Who Is Jack Jones?
Jones, 28, has been around the league since New England selected him in the fourth round of the 2022 draft. Last season with Miami, he was a full-time starter, appearing in all 17 games while racking up one interception, two forced fumbles, and six passes defensed. The guy can make plays when given the opportunity. His strength? Press man coverage, which is exactly what new coordinator Raheem Morris loves to run with the 49ers. That scheme alignment could unlock another level in his game.

Jones has had his ups and downs in the NFL. He showed promise as a rookie in New England but got cut midway through his second season. Then came his best stretch: a stint with Las Vegas where he absolutely torched the Chargers and Chiefs, returning two interceptions for touchdowns in back-to-back wins. That was the flash of brilliance that made people believe in his potential. But it didn't last. The following season, his aggressive style bit him hard. According to Pro Football Focus, his aggressive play contributed to 10 touchdowns allowed in coverage. Las Vegas released him last April, and he landed with Miami for the season that just wrapped.
Over four seasons in the NFL, Jones has eight interceptions and 33 passes defensed to his name. His four career pick-sixes rank second most in the league since he entered in 2022. The production is real. Now he slots in behind starters Deommodore Lenoir and Renardo Green at outside cornerback, giving San Francisco some solid depth for the stretch ahead.
