Premier Brisbane jockey Jeff Lloyd will need a doctor's clearance before he can chase another milestone at Doomben.
Lloyd, who has been battling a virus for a week, won on Te Amo at Ipswich on Wednesday to take him to 98 Queensland victories for the season.
He was later stood down with illness and will need a doctor's certificate before he can take his rides on Saturday.
Lloyd got through the Doomben meeting last Saturday but did not ride at the Sunshine Coast the following day.
He has a strong book of rides at Doomben with 100 Queensland winners in his sights for the third season in a row.
It is a likely a decision on his health will be made on Friday
