Triple Melbourne Cup-winning rider Glen Boss will be back in Melbourne to ride an international runner in Saturday's Group I Caulfield Stakes (2000m).
Boss will ride Riven Light for Irish trainer Willie Mullins in the Caulfield Stakes and will again be aboard Epsom Handicap runner-up Tom Melbourne in the Group I Toorak Handicap.
Mullins confirmed Boss's booking in the Racing Post on Sunday but added the Caulfield Stakes would determine the rest of Riven Light's Melbourne campaign.
Riven Light is among Cox Plate entries despite notching his maiden stakes win when narrowly successful at Listowel on September 13.
Boss will also be aboard Kiwi three-year-old Summer Passage in the Caulfield Guineas.
