Adrian Maguire will make a decision on his Martell Grand National mount tomorrow. The Meathman has the choice of Ferdy Murphy's two runners, Addington Boy and Paddy's Return, with JP McNamara set to take the ride on which ever one he discards.

"I'm not rushing Adrian," Murphy said yesterday. "He'll make his mind up on Tuesday when he comes here to school them and ride them in work.

"It depends on quite a few things. They both want top of the ground but if the weights go up then that would improve Paddy's Return's chances."

Addington Boy has run with distinction in the last two Grand Nationals, finishing fourth to Bobbyjo in 1999 and fifth behind Papillon 12 months ago while Paddy's Return has also run well over the course having been placed third in the Becher Chase earlier this season.

"I'm absolutely 100 per cent pleased with their preparations," Murphy added.

Paddy's Return is generally quoted at 20 to 1 while Addington Boy's chances are rated 33 to 1.

Mick Fitzgerald, who gave up his remaining rides after a fall in the opening race at Ascot on Saturday, will return to action on Wednesday. Fitzgerald is due to partner Esprit de Cotte for his boss Nicky Henderson in the Grand National on Saturday.
