Jack Jones: Everything you need to know

Jones signed a one-year contract with San Francisco on Friday, Ian Rapoport of NFL Network reports. Jones started all 17 regular-season games for the Dolphins in 2025, in which span he totaled a career-high 77 tackles (49 solo) plus six passes defensed, including one interception, and two forced fumbles. Now with the 49ers, Jones could provide Renardo Green with competition for outside-cornerback snaps across from Deommodore Lenoir, or challenge Darrell Luter for a depth role.

Jones made four tackles (two solo) during Sunday's 38-10 loss to the Patriots. Jones compiled a career-high 77 tackles (49 solo) across 17 regular-season appearances in 2025, plus six passes defensed, including one interception, and two forced fumbles. He's slated to become an unrestricted free agent this offseason, but given the tremendous amount of question marks looming for the Dolphins' cornerback corps, both sides could have mutual interest in a reunion.

Jones logged 10 tackles (eight solo) and a pass defense during the Dolphins' 20-17 win over the Buccaneers on Sunday. Jones recorded double-digit tackles for the first time in his four-year NFL career Sunday, and his eight solo stops were also a career best. He joined the Dolphins on a one-year contract in late July after being released by the Raiders in April, and through 16 regular-season games he has accumulated 73 tackles (47 solo), six pass defenses and two forced fumbles.
