Top Queensland sprinter Tambo's Mate has been injured and will miss the Group One Stradbroke Handicap.
Tambo's Mate had beaten the ballot for the Stradbroke at Eagle Farm on June 6 after winning the Group Three BRC Sprint at Doomben three weeks ago.
The gelding ran seventh in the Group Two Victory Stakes at Eagle Farm last Saturday.
Trainer Stuart Kendrick said jockey Matt McGillivray felt there was something wrong when he returned to scale after the Victory Stakes.
"We let him cool down and had him scanned. He has wrenched a joint," Kendrick said.
"It is very swollen and he will need three months in the paddock.
"I thought he was going to be in the finish at the 250 metres but he stopped. He must have done it around then.
"Hopefully we can get him back for the summer."
Tambo's Mate rates as one of Queensland's most improved horses, going from a maiden success to stakes winner in the space of 12 months.
