Kieren Fallon is set to team up with old ally Sir Michael Stoute to partner Across The Stars in the Derby at Epsom.
Fallon was Stoute's principal jockey between 1999 and 2004, riding two Derby winners for the trainer - Kris Kin (2003) and North Light (2004).
Kris Kin was owned by Saeed Suhail, in whose colours Across The Stars also runs, and Suhail's racing manager Bruce Raymond said he was pleased to see the team reunited.
"Kieren rode him this morning and I gather he will ride him again when Sir Michael works him tomorrow," Raymond said.
"If he runs in the Derby, I'm sure Kieren Fallon will ride him.
"He won on Kris Kin for Saeed Suhail, so he was very keen to use him and he obviously has plenty of experience around Epsom.
"It's good to have him and to reunite the winning combination of the three of them."
Across The Stars has won one of his four starts and most recently finished third in the Lingfield Derby Trial after a somewhat troubled passage.
Fallon, a six-time British champion, recently returned to European racing from America, taking a job with Michael O'Callaghan in Ireland.
