So You Think may be losing favour with Melbourne Cup punters but he remains number one with those who matter most.

Owner Dato Tan Chin Nam says a final decision on whether the dual Cox Plate winner runs in Tuesday's Cup will be left to trainer Bart Cummings with the chances currently at 90 per cent.

So You Think was displaced as favourite for the Cup on Wednesday with last year's winner Shocking regaining top billing.

Doubts about So You Think running 3200 metres seem behind his loss of favour but Dato Tan says no-one should underestimate him.

"He is a good horse and a good horse can overcome anything," Dato Tan said.

"He is a champion and if he can stay he will win.

"At the moment he is 90 per cent to run.

"I'm not the tiger, the trainer is and the trainer has the last say."

Dato Tan said the forecast of wet weather and a soft track would not be a reason to keep him at home.

"He'll run rain or shine," he said.

"A horse like this must be given a chance."

Dato Tan is the Melbourne Cup's most successful owner having won four with Think Big (1974 and `75), Saintly (1996) and Viewed two years ago, all of course trained by Cummings.

"I can't dream of a better horse," he said.

"He's the best.

"He won two Cox Plates at two and three - not three and four, he won't be four until the 11th of November.

"So that must be a good horse."

The good horse is at $1.60 to win his clash with Shocking ($6) in Saturday's Mackinnon Stakes - the traditional lead-in to the Melbourne Cup for Cummings' Melbourne Cup runners.

Shoot Out, who is also headed to the Cup, is next at $10 with his jockey Corey Brown having a scare at Canterbury races on Wednesday when he was headbutted by one of his mounts.

Brown was stood down from his final ride but said he was sure he would be fine come Saturday.

"I'll be sweet for Saturday," Brown said.

"The horse flung its head back and headbutted me. My neck is sore and when the doctor pushed and poked I got a headache straight away.

"It's not the end of the world or anything and I'll just have to go and see my chiropractor."
