Skysports.com understands Doncaster are poised to sign West Ham defender Herita Ilunga on loan.
New Doncaster boss Dean Saunders has lined up a deal for the full-back as he looks to bolster his defensive options.
Ilunga has found himself down the pecking order at West Ham with George McCartney first-choice left-back under Sam Allardyce.
The 29-year-old has not featured in the Hammers first team since the shock Carling Cup defeat to Aldershot and Sam Allardyce is thought to be willing to loan him out.
Doncaster are thought to have agreed a three-month loan deal for the left-back and he will become Saunders' second signing after Pascal Chimbonda since his arrival as manager.
