Veteran running back Shonn Greene was already facing an uncertain role after the Tennessee Titans selected the 2014 NFL Draft's first running back, Bishop Sankey, at No. 54 overall.
Now Greene has another obstacle to lead-back duties.
The 28-year-old back is expected to miss the entirety of the Titans' organized team activities this spring after undergoing surgery on his right knee, the Tennessean's Jim Wyatt reports.
This is the same knee that required arthroscopic surgery last September, forcing Greene to miss five games.
Greene complained of soreness and experienced swelling in the knee after the Titans' recent three-day minicamp, per Wyatt.
It's a troubling sign, as new coach Ken Whisenhunt is counting on Greene to team with Sankey and Dexter McCluster in a three-pronged attack to replace Chris Johnson in the backfield.
If Sankey impresses coaches in offseason practices, Greene could find himself tumbling down the depth chart by the time he returns to the field for training camp.
