Former footballer Mick Quinn hit the woodwork when he began his training career at Southwell yesterday afternoon, when Katie's Cracker went down by half a length in a driving finish.
And it was old footballing buddies Mick Channon and Kevin Keegan who foiled hopes of a dream start as Cutting Anshake held on to take the Antony and Cleopatra Selling Stakes from the Quinn runner.
