The Jaguars kept Jones over C.J. Beathard (groin) as the No. 2 QB on their initial 53-man roster, Justin Barney of News4Jax reports.
Jones completed 38 of 52 passes (73.1 percent) for 421 yards (8.1 YPA) and three touchdowns in three preseason games, while Beathard attempted just 21 passes before a groin injury knocked him out of action. Beathard was then released Tuesday with an injury settlement, leaving Jones as the backup to Trevor Lawrence heading into Week 1.
