The jockey was stood down from 27 January after he was blamed for an incident in which Tom Dascombe, on Country Tarquin, was almost forced out by Maguire's mount, Adilov, approaching the first flight in the novices' hurdle.
Maguire had until 5pm last night to lodge an appeal. He is awaiting advice from Michael Caulfield, the Jockeys' Association secretary. "Michael is going to look at a video of the race tonight," Maguire said, "and we will take things from there."
Tony Culhane and John Bramhill were banned for five and two days respectively for improper and careless riding respectively in Southwell's finale yesterday. The jockeys' mounts finished second and third.
