The Caulfield and Melbourne Cup favourite Incentivise is out for the spring.
Managing part-owner Ozzie Kheir confirmed the news on Monday morning, claiming the long months of rehabilitation this year have taken a toll on the horse with trainer Peter Moody ruling the horse "mentally tired".
"We are disappointed butnot devastated," Kheir said.
"Peter just said he thinks the horse is mentally tired despite it being the best the horse has ever looked.
"He looks stronger and bigger and his feet are 100 per cent but he (Moody) said he's just been through the ringer so for long that mentally, he won't get through a prep."
Last year's Caulfield Cup winner and Melbourne Cup runner-up has been in and out of rehabilitation programs since February after pulling up with a few injury issues after his amazing spring, when he won three group 1 races in Melbourne.
"The horse has been thoroughly scanned and all is good but we've made the decision to give him a let-up," Kheir said.
"He was doing a fair bit of work in his rehab and we would have liked to have given him four to six weeks after rehab but he only got two to three weeks.
