The Tennessee Titans continue to add pieces to their roster in free agency, reaching deals with former New York Jets running back Shonn Greene and former Detroit Lions defensive tackle Sammie Lee Hill, per TitanInsider.com.

Greene, who has two 1,000-yard seasons to his credit, will back up Chris Johnson in Tennessee, thanks to a three-year, $10 million deal.

Hill will fill in on the defensive line rotation and his size (6-3, 329) gives the Titans a big body in the middle to pair with Jurrell Casey. Hill's deal is for $11.4 million over three years with $4 million guaranteed.
