The 49ers are set to sign Jones to a contract, Tom Pelissero of NFL Network reports.
Jones didn't play at all last season after breaking a bone in his neck in late July while with the Cowboys. He's presumably back to health and could compete for a starting role with the 49ers. During his tenure with the Dolphins from 2021 to 2024, Jones started 30 of the 49 games in which he appeared.
