The Miami Dolphins added needed help to their secondary on Saturday, signing cornerback Jack Jones to a one-year deal. Jones had 69 tackles, three interceptions— one returned for a touchdown — and 15 pass breakups in 16 starts for the Raiders last season. The Raiders released him earlier this year. A fourth-round draft pick by New England in 2022, Jones played two up-and-down seasons for the Patriots before being released and claimed off waivers by Las Vegas in 2023.
