A late setback has scuppered the G1 Qatar Prix de l'Arc de Triomphe chances of Estrange (Night Of Thunder), who will now miss the race, leaving a field of 17. Due to start widest of all in gate 18, she delivered a dirty scope in the lead up to the race.Owned by Cheveley Park Stud and trained by David O'Meara, the grey filly has won multiple group races and was second to one of the favourites in Minnie Hauk (Frankel) in the G1 Yorkshire Oaks last out.O'Meara told the PA news agency, “We're all devastated. She worked earlier in the week and worked great and it looked like the rain was coming for her which was ideal.“This morning she was coughing after exercise and I scoped her and she was dirty – we don't have enough time to get her cleaned up.”Estrange could yet be seen this season in the G1 QIPCO British Champions Fillies & Mares Stakes at Ascot on October 18.He added, “We'll see. It would be a guess. I just don't know. We'll put her on some antibiotics and just keep her ticking over and see where we are in a week or so.”The post Setback Forces Estrange To Miss The Arc appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
