Doncaster Rovers director of football Mickey Walker has left the club after 12 years.
Walker was assistant manager to Dave Penney as Rovers earned back-to-back promotions in 2002/03 and 2003/04.
He told the club website: "There's no bitterness in the parting. I wish Dean Saunders and the boys all the best for next season.
"I still believe I have something to offer with my extensive experience and my contacts book."
