The eight-year-old led the field for much of the two-mile journey in the Grade One contest and although he was headed by the Gary Moore-trained Sire De Grugy before the home turn, he rallied for pressure in the straight.
Henry de Bromhead’s Irish raider was still in with a chance of victory before being broadsided in mid-air by the eventual winner jumping the final fence and after a battle on the run-in, Sire De Grugy passed the post three-quarters of a length in front.
De Bromhead confirmed on Sunday an appeal was being considered and that he believed the interference cost his charge victory.
Rowley-Williams said on Monday afternoon: “Everything is still being considered. I believe we have seven days to decide, but we won’t leave it that long. We’ll make a decision by the end of the week.
“I’m having discussions with my solicitor and we’re waiting for some data to come back. There won’t be a decision today.”
Meanwhile Paddy Power Gold Cup winner Annacotty is among 18 horses left in the Caspian Caviar Gold Cup at Cheltenham on Saturday at Monday’s confirmation stage.
The seven-year-old was successful on his first start since joining trainer Alan King from Martin Keighley’s team and could now bid to become the first horse to win both races since Exotic Dancer in 2006. King is also represented by Turn Over Sivola in this valuable handicap chase over an extended two and a half miles.
With King’s Smad Place and also Wishfull Thinking being withdrawn at the five-day stage, the weights will go up 6lb and are now headed by the Paul Nicholls-trained Sound Investement.
Nicholls has two other possibles in Salubrious, who won at Carlisle recently on his first start for 13 months, and Paddy Power Gold Cup sixth Art Mauresque.
Most of the leading fancies have stood their ground. They include Irish Cavalier, who took fifth place behind Annacotty last month.
Philip Hobbs has two strong candidates in Champagne West and Village Vic, who could both line up, according to stable jockey Richard Johnson.
“It looks like both Champagne West and Village Vic will take their chance, the title-chasing jockey told www.betway.com.
“Champagne West was a high class novice last season. He’s won twice around Cheltenham, seems in great order at home and won’t mind the ground.
“Village Vic has been in great form this term and we’re hopeful he’s still going the right way.
“It’s the perfect race for both of them and it’s obviously nice to have two decent chances. It’s just a shame they’re in the same race.”
There are three remaining Irish entries, Willie Mullins’ Mozoltov, Texas Jack, trained by Noel Meade, and Arthur Moore’s Pass The Hat.
