The Tennessean suggests that Greene's roster spot could be in jeopardy following the team's selection of David Cobb in the recent NFL draft. It's a notion echoed by ESPN.com, though the veteran running back -- who has been away from the team's voluntary organized team activities to attend to a family matter -- remains slated to participate in the Titans' mandatory minicamp, which runs from June 16-18. With Bishop Sankey still atop the team's RB depth chart, Greene could well be squeezed out by Cobb, a fellow big back, assuming the rookie is able to stay healthy in advance of the 2015 season.
