Mr Brightside will not be pursuing a third consecutive win in the Group 2 PB Lawrence Stakes (1400m) at Caulfield in August.
Co-trainer Ben Hayes mentioned that the rising seven-year-old gelding had returned to work after gaining 41 kilograms during his spell.
He will start stepping up to even time in his work next week.
“We’ll miss the Lawrence Stakes this year. We just wanted to give him some more time,” Hayes, who trains with his brothers JD and Will, told Racing.com.
“He’s carrying some nice condition, but that’s a good position to be in at this time. He’ll be starting evens next week.
“We are really happy with him; he’s put on some good weight, can’t fault him. He’s a happy horse and he’s working in great fashion.”
Hayes added that Mr Brightside would make his return in the Group 1 Memsie Stakes (1400m) at Caulfield on September 7, a race he won second-up last year.
