Scunthorpe have opened contract talks with three players who all have a year to run on their current deals. They are midfielder Matt Sparrow, 23, defender Marcus Williams, 21, and winger Cleveland Taylor, 23.
"We don't want players to run out of contract," manager Nigel Adkins told BBC Radio Humberside.
"We've had initial conversations with their agents, as we need to make sure the good players at our club are not going to leave on a Bosman."
