49ers signed CB Jack Jones, formerly of the Dolphins.

10 April 2026

This is a one-year contract for Jones. He entered the NFL as a 2022 fourth-round pick with the Patriots. He was waived in November 2023 after dealing with a lengthy hamstring injury. The Raiders added him right away, but eventually waived him in April 2025. He was signed by the Dolphins during the 2025 offseason. PFF credits him with six forced incompletions and one interception last year. Jones has a chance to compete for a starting role here.
