Former Don Josh Magennis has signed for Kilmarnock on a three-year deal.
The 23-year-old had been training with the Ayrshire club after being released by Aberdeen in the summer.
He spent the second half of last season on loan at fellow Scottish Premiership side St Mirren, making 13 appearances, but failing to score.
Magennis has been capped three times by Northern Ireland and was recently in the squad for the matches against Uruguay and Chile in South America.
He is manager Allan Johnston’s fifth summer signing, and will play up front with another former Aberdeen attacker, Lee Miller, who has signed a two-year deal.
Killie have also signed former England under-20 international Tope Obadeyi on three-year contract.
Championship side Dumbarton are keen to sign Aberdeen goalkeeper Danny Rogers on loan after he impressed in games against Stenhousemuir and Hamilton Accies.
Manager Ian Murray said: “Danny did well in his first game and even better against Hamilton so I will be looking to speak to Derek McInnes about him coming here once he has the European tie out of the way.
“Danny is very highly thought of by the people at Aberdeen and this could be a win-win situation where we have great competition for our goalkeeping position and their goalkeeper can gain experience.”
