The officials ruled he had used his whip above the permitted level from the second-last when winning The Ladbroke on the Gordon Elliott-trained Bayan.
It was an emotional success for Condon, who has been plagued by injuries and was having just his third ride back since a heavy fall at Cork in August.
The jockey suffered three fractured vertebrae in the spill and initially feared he may never ride again after suffering a rare condition called spinal concussion, which briefly left him unable to move from the neck down.
Silviniaco Conti meanwhile spearheads a list of 10 possible runners for the William Hill King George VI Chase at Kempton on Friday.

Philip Hobbs has left in Wishfull Thinking and Menorah, while Paddy Power Gold Cup runner-up Johns Spirit may be given the chance to shine by Jonjo O’Neill.
Double Ross is also still in the hat for the Nigel Twiston-Davies team.
Daryl Jacob is looking forward to the ride on Cue Card, and is on a high after Reve De Sivola’s win in the Long Walk at Ascot.
He said: “I can’t wait to ride him. I’m schooling him on Monday. He seems in great form at home. I must admit I thought going to Haydock (Betfair Chase) he’d win and I was obviously a bit disappointed he didn’t (fourth to Silviniaco Conti).
“I thought he could not get any better going into Haydock, but Colin and Joe (Tizzard) keep saying ‘be confident, be confident’ and I am confident, because I have confidence in them.
“They are great trainers, so I have every confidence they are going to bring the horse back to his best.”
Evan Williams too is looking forward to a long-term plan coming to fruition when One In A Milan lines-up for the Coral Welsh Grand National at Chepstow on Saturday.

The Llancarfan trainer has had the marathon handicap chase in mind again for the nine-year-old since he fell at Becher’s on the second circuit in the Crabbie’s Grand National at Aintree in April.

“The weights will go up, we’ve yet to decide who will ride him. We might claim off him. We’ll see closer to the day,” said Williams.
“This has been his target since the Grand National.”
Oliver Sherwood reports Puffin Billy to be none the worse for his heavy fall at Ascot on Saturday.
The six-year-old, who came a cropper at the final fence in the David Johnson Shawbrook Bank Graduation Chase won by Irish Saint, was given the thumbs up after being checked over.
