Elko (knee) has been cleared to begin a rehab assignment with High-A Winston-Salem, James Fegan of SoxMachine.com reports.
Elko underwent surgery last October to repair a torn ACL in his right knee and is finally ready to test out his rebuilt knee in games. The 27-year-old should eventually be assigned to Triple-A Charlotte, where he will give the White Sox organizational depth at first base. Elko is no longer on Chicago's 40-man roster, having been non-tendered over the winter before re-signing on a minor-league contract.
