Black Heart Bart has been scratched from the Blamey Stakes after apparently becoming cast in his box and taking skin off a leg.
His withdrawal leaves a six-horse field for Saturday's Group Two feature at Flemington with Black Heart Bart's Darren Weir-trained stablemate the new $1.95 favourite.
Another stablemate, Palentino, is at $2.50 with the other four runners all in double figures.
The mishap throws doubt over Black Heart Bart for the Doncaster Mile on April 1 with the six-year-old the 57kg topweight in the $3 million race at Randwick.
