Derby County have signed Kilmarnock goalkeeper Devlin MacKay on loan until January 2016, the Scottish Premiership club have confirmed.
The 18-year-old has featured on a number of occasions for the club's development team and was recently named on the bench for their first-team game against Aberdeen.
Kilmarnock goalkeeping coach Billy Thomson told the club's official website: "This is a great opportunity for Devlin. It will give him a whole new outlook as he meets new people and trains in a different environment.
"He is going to a big club and I am confident he will come back a better keeper. We wish him all the best."
Killie have gone on to recall Conor Brennan from his loan spell at Stranraer to cover for MacKenzie's absence.
