Jones is signing with the Raiders, Dale Lolley of DKPittsburghSports.com reports.
The 2013 fourth-round pick had a lengthy run as the backup quarterback in Pittsburgh, making five starts in five years before he was unseated by Joshua Dobbs and Mason Rudolph during the 2018 preseason. Jones spent a couple weeks with the Jaguars in November and now will head to Oakland to compete against Mike Glennon and Nathan Peterman for the backup job behind Derek Carr.
