Aberdeen have announced that striker Duk has officially returned to the club following an extended absence without leave.
In July the Dons revealed they were taking disciplinary action against the 24-year-old who "absent without permission" and "refused to engage" with the club when they made contact.
However, after apologising for his actions, Duk - who wanted to leave in the summer - is back training with the first-team, as he now enters the final year of his Aberdeen contract.
The Cape Verde forward - who has scored 25 goals in 95 appearances since joining Aberdeen from Benfica - said: "I would like to sincerely apologise to everyone associated with Aberdeen for my absence over the last period
"I deeply regret being away. I am grateful to the club, the manager, my team-mates and supporters for giving me a chance. I will work hard every day to try and help the team."
TrendingDons CEO Alan Burrows added: "This has been a very challenging situation for all involved and it was important for everyone that Duk understood and accepted that he shall return to Aberdeen and his behaviour was not what we would expect from any Aberdeen player.
"He has owned the situation, returned and convinced us all that he not only recognises those things, but he is hungry to help the team and the club going forward and accomplish this season's objectives.
"The board, football management, the players and staff have accepted this. I hope our supporters can do the same."
Aberdeen are second in the Scottish Premiership after winning all four league games under Jimmy Thelin, with the new manager keen to get him in his squad.
Manager Jimmy Thelin said: "Aberdeen is a family club built in a family tradition. At times, people in your family might make a mistake and, on those occasions, you rally around and support.
"Duk has demonstrated his contrition over this situation and understands his behaviour falls well below the standards we expect here so it is our job now to work with him in training and get him ready to compete for a place in the squad again."
