Jones (concussion) was a full participant in the Titan's practice Wednesday, Shaun Calderon of USA Today reports.
Jones has been sidelined for each of the last two games after popping up with a concussion during practice Week 11. While it's encouraging to see the 33-year-old return to practice in full, it's unclear if he's officially cleared protocols yet. Expect Jones to reprise a starting center role when he's healthy.
