The wide receiver made the headlines last week after he was arrested for failing a random drug test following legal troubles last year over cocaine possession.
The Jaguars released the following statements:
All roster moves are decisions we feel are in the best interest of the organization, Jaguars General Manager Gene Smith said. This decision is a result of our ongoing player and roster evaluations. We expect responsibility and accountability, and those are important qualities as we continue the process of building this team.
"On a day when players returned to Jacksonville Municipal Stadium to undergo physical assessments that kick off new strength coach Luke Richesson's conditioning program, Jones was cut by the team following a week in an Arkansas jail for violation of his probation. Thus ends an attempt to convert Jones from a college quarterback to a pro pass-catcher. He was the 21st overall pick of the 2005 draft."
