ESPN's Len Pasquarelli claims that the contract contains a voidable sixth year but the Lions have avoided using voidable years in their contracts in the past and Pasquarelli's comments could be nothing more than speculation.
Detroit is also believed to have come to terms with third-round pick cornerback Keith Smith and fourth-round pick linebacker Alex Lewis. If that is the case, that would leave only wide receiver Roy Williams, the team's other first round pick (7th overall) as the only player left to come to terms.
Jones is expected to immediately become the team's feature back and team with second-year man Artose Pinner to form the team's running back tandem.
Sources are telling Lionsfans.com that Williams and the Lions should come to a deal perhaps as soon as tomorrow.
Smith is expected to compete with returning corner Andre Goodman and Rod Babers for the nickle back position behind starters Dre' Bly and Fernando Bryant. Returning corner Chris Cash is expected to start the season on PUP after electing not to undergo surgery for ligament damage in his right knee.
Lewis is expected to start out as a special teams player and eventually work his way into the playing group.
