Collonges Ayr raid

NEPTUNE Collonges is set to carry top weight in Saturday’s Coral Scottish Grand National at Ayr.

Paul Nicholls’ 10-year-old won the Argento Chase in January before finishing eighth in the Cheltenham Gold Cup, a race he had been third and fourth in earlier in his career.

Howard Johnson has left in Tidal Bay, who was still travelling well when getting rid of Brian Hughes at the 10th fence at Aintree.
