Group One winner Mighty Boss has died after a bout of colic.

The Mick Price-trained entire won two of his 17 career starts, including the Gr.1 Caulfield Guineas (1600m).

“Terribly sad for Mr Yaseen and everyone at the stable to lose Mighty Boss to colic,” Price said on Twitter.

“(He was) a magnificent colt with most unique personality - he will be sorely missed.”

The son of Not A Single Doubt was purchased by his trainer out of Curraghmore’s 2016 New Zealand Bloodstock Premier Yearling Sale draft for $180,000.
