Deano, Wilder, Beattie, Bent, who else has done it?
Deano had 3 spells I know, but who else has returned?
Kozluk of course. Anybody else ?
Off the top of my head:
Keith Edwards (the most famous - 75-78 and 81-86)
Jon Harley (2 loan spells in 02 and 03 and then permanently in 04)
Jonathan Hunt (loan in 98 and then permanently in 99)
Andy Campbell (2 loan spells in 98 and 99)
Dean Windass (loan in 02 and then permanently in 03)
Wayne Quinn (permanently 97-01 and then back on loan in 02-03)
Ian Bennett (loan in 04-05 then permanently in 06)
Paul Gerrard (loan in 03-04 and then permanently in 06)
Neil Collins (loan in 05-06 and then permanetly in 2011)
Joe Kitchen - our one time all time leading scorer pre WWI - we flogged him to Rotherham around 1919 and then got him back the next year
Des Thompson - 50's reserve goalie who we released in 62, but then got him back from Buxton on a short term contract in 63 when both Hodgkinson and Widdowson were injured
Jeff King - released in auutumn 82 due to "personal" issues, then re-signed on New Year's Day and scored on his return that day
Rob Ullathorne - signed Nov 00, but released at the end of the season when new terms could not be agreed. Came back in Jan 02 with his tail between his legs.
Edit:
yep
Clive Mendonca - 86-88, sold to Rotherham and re-signed 91 before being flogged to Grimbsy
Billy Sharp we all know about.
