The bite...Black Piranha, a top contender for Sat's big Doncaster Mile, has returned a positive to the prohibited substance phenylbutazone. Stewards say a swab sample was taken from the Con Karakatsanis-trained galloper before he ran 2nd to Hot Danish in the Grp 2 Canterbury Stakes at Rosehill on Mar 21. They allege it showed the presence of phenylbutazone and oxyphenbutazone. An inquiry date is yet to be set. BP is a 25/1 chance for the Doncaster.
