Hayes fills Stack job while Lordan joins Ballydoyle
Chris Hayes will be linking up with Fozzy Stack as first jockey next season while maintaining his long association with Kevin Prendergast, for whom he has ridden since his days as an apprentice.
The 2017 season will be Stack's first as a trainer after he takes over from his father, Tommy, who will be retiring at the end of next month.
Hayes said: "I'll be riding for Fozzy next year while I'll be maintaining my link with the boss [Prendergast] and riding for him when I can.
"It will be a good balance, riding for a new yard and for the trainer I started with, and I'm really looking forward to it."
Hayes, 29, who was champion apprentice in Ireland on three occasions, has ridden two Classic winners including winning this year's Irish 2,000 Guineas on Awtaad for Prendergast.
"I'm back home from Dubai with a broken wrist and when that mends, I'll be going back there to ride early next month, " Hayes said.
Wayne Lordan, who has long been associated with the Stack stable, and also with David Wachman, who recently retired from training, is joining the team of riders at Ballydoyle for the 2017 season.
Lordan, who has ridden for Aidan O'Brien many times, said: "I'm going to Ballydoyle as part of their team of riders.
"I'll be riding work and trying to make best use of whatever opportunities might come my way. I'll be putting my head down and giving the job 100 per cent.
"Ryan McElligott will still be my agent and I'll be riding for other trainers as often as I can."
