Chris Johnson has said that he does not know how the Tennessee Titans will use new signing Shonn Greene.

The former New York Jets running back joined the AFC South side earlier this month, signing a three-year contract.

The Titans' 2012 rushing yards leader told The Tennessean: "I have never been a big fan of the two-back system, so I don't know how we plan on using him.

"I'm not afraid of competition, but I was thinking we'd maybe get a draft pick for the other back. And you don't give a guy that kind of money to be just a goalline guy and in tough-yardage situations. So we'll see what happens."

Johnson has recorded over 1,000 rushing yards in each of his five seasons with the Titans, while Greene has reached the same milestone during his last two years with the Jets.
