Dundee have secured the signature of Kilmarnock's Mark O'Hara on a two year deal. He made s Killie debut as a substitute against Stenhousemuir in 2012 aged 16. Shortly after that game, he made his first start the club in a memorable game when they beat Celtic 2-0 at Celtic Park, giving Killie their first win there since 1955. Over the past four seasons, Mark has gone on to play just short of 100 games for the Rugby Park club, including 33 times last season. He has also managed to pick up Scotland caps at both under 19 and under 21 level during his time with the club.
Manager Paul Hartley said: "He is a player that fits the bill perfectly. Mark is at the right age and is someone we think we can work with and develop. He is versatile and at a young age has played alot of games already. He can play right back but we want to develop him in the middle of the park. He had a year left on his contract at Killie so we are delighted to secure his signing."
