Paul Nicholls has confirmed Tidal Bay as an intended runner in Saturday's Coral Scottish Grand National at Ayr.

The 13-year-old unseated his rider early in the Grand National at Aintree last week and is set to make a swift return after pleasing his handler in a schooling session this morning.

Nicholls tweeted: "Tidal Bay just schooled well and runs Saturday at Ayr."

Tidal Bay, once again the mount of Sam Twiston-Davies, heads a maximum field of 30 plus two reserves in this weekend's extended four-mile race.

Nicholls also saddles Sam Winner, who will be ridden by Nick Scholfield.

Leading Scottish trainer Lucinda Russell has two major contenders in Green Flag and Lie Forrit, while the Harry Fry-trained Mendip Express is also among the market principals.

The two reserves are outsiders Top Smart and Scotswell, who could potentially get a run if there are any withdrawals before a deadline of 9am on Friday.
