Hearts left-back Harry Milne could face a lengthy lay-off after suffering a knee injury in training on Wednesday.

Milne misses out on Hearts' Conference League game at Trabzonspor and will undergo a scan to determine the severity of the damage, amid reports it is a suspected ACL injury.

"Yeah, unbelievable actually, because without contact, he got an injury," head coach Wouter Vrancken told BBC Scotland.

"So we'll see probably when we're back when we can make a scan to see how it is.

"It's crazy because now it's not about fatigue, it's not about contact, it's not about anything, this with him is just bad luck now. It's his knee."

Vrancken added that midfielder Laurent Mendy and defender Stephen Kingsley have dropped to the bench as they are both carrying knocks from the defeat to Celtic on Sunday.

"I don't want anybody to be out long term, especially when you see now, also with Laurent Mendy not being totally fit after a kick he got at the weekend," he said.

"So we'll see if we're going to need him because it's always a risk there with him.

"With Kingsley, same with another area, but also there it's a big risk to play him so many games because of his history, of course."
