Scunthorpe United manager Nigel Adkins has told out-of-contract defender Andy Butler to decide on his future.

The club has offered Butler a three-year deal but there is interest from other clubs and at 24 the defender could leave the club for free.

"I am ever the optimist," Adkins told the Scunthorpe Telegraph.

"Andy knows what our position is. He knows what is on the table and he knows that we do now need a decision from him.

"Hopefully that will come in the early part of next week."

Butler made his debut as an 18-year-old and the new deal at Glanford Park would culminate in a testimonial match.
