Ruby Walsh will ride Zarkandar in Saturday's Betfair Hurdle after he was allowed to defer his suspension.
Walsh had lost his appeal against a three-day ban, incurred for careless riding at Cheltenham on 28 January.
He was found guilty of interference when partnering Pearl Swan to victory in the JCB Triumph Hurdle Trial.
That meant he was set to miss the event at Newbury this Saturday, but he has now got what he describes as a "get out of jail free card."
As there was originally no Grade One race on the card, Walsh was set to be on the sidelines for Saturday's event.
However, the British Horseracing Authority (BHA) has announced that the Grade One Scilly Isles Novices' Chase would be transferred from last Saturday's abandoned Sandown card to this weekend's fixture at Newbury.
BHA rules state that Walsh can defer his ban on days where Grade One races are run.
Walsh was thrilled with the news, writing on Twitter: "Looking like I have got a get out of jail card for Saturday! Grade 1 Scilly Isles is my ticket to at least take part. Happy days."
