Jones won't practice Wednesday due to hamstring tightness, Rob Demovsky of ESPN.com reports.
The extent of Jones' injury is uncertain, but the report notes it is "not expected to be anything long term." With that in mind, Jones may be withheld from action for a few more days, but the hamstring issue doesn't look like anything that will affect his status for Week 1. With both Jones and Jamaal Williams -- also dealing with a hamstring injury -- banged up, rookie Dexter Williams will have an opportunity to see more snaps with the first team.
