Ante-post favourite Gallant Oscar is among a maximum field of 30 runners in the Coral Scottish Grand National at Ayr on Saturday.
News emerged on Wednesday evening leading owner JP McManus had stepped in to buy the Tony Martin-trained nine-year-old, who was last seen finishing third in a fiercely competitive handicap chase at the Cheltenham Festival.
With Tony McCoy unable to do the weight, Paul Carberry has been booked for the ride, leaving the soon-to-retire champion jockey free to partner Benvolio for Paul Nicholls.
Nicholls also runs top-weight Sam Winner, the mount of Sam Twiston-Davies.
Other major contenders include the Jonjo O'Neill trained-Catching On, David Pipe's Broadway Buffalo and last year's winner Al Co, trained by Peter Bowen.
Man With Van and Drop Out Joe are the last two horses in the final field, with Vintage Star and Carrigdhoun the respective first and second reserves.
