Aberdeen youngster Ryan Jack has vowed to return from injury stronger than ever after being ruled out until after the new year with a metatarsal injury.
Jack, 20, picked up the injury in Scotland Under-21s' 2-0 defeat to USA Under-21s in Marbella on Friday, while captaining the side for the first time in his career.
The midfielder will need surgery and faces up to 12 weeks out on the sidelines after X-rays revealed he had fractured a metatarsal for the third time in his career.
And Jack, who was out for 11 months from the same injury in 2008, is determined to make an impact on his return for the Scottish Premier League run-in.
"I know this is serious as I've done it before. I'm gutted but I will come back fitter and stronger," Jack told the Daily Record.
Jack has played a major role in Aberdeen's impressive nine-match unbeaten run which has seen them rise up to third in the league.
And Dons' boss Craig Brown has revealed his disappointment at losing such an influential player from his playing squad.
"It is a pity for Ryan and for ourselves. He is an important player for us as he can perform in a number of positions," Brown said.
"It is a blow but the important thing is he has the surgery and gets back to full fitness so he will be available after Christmas."
