Despite his disappointment, Heckingbottom is confident that the defender remains focused on the new season with the Reds.
On the situation with Yiadom, out of contract next summer, Heckingbottom said: "He has rejected a new deal at the club. He wants to see out his contract and see what things are there for him. It was similar when we took him from Barnet.
"One thing is for sure, we will have a hungry player on our hands who is trying to impress everybody to earn the best possible contract where he can, whether it is here or elsewhere.
