Chacun Pour Soi pushed to 10/1 from from 11/2 after Tingle Creek last.
Willie Mullins' Chacun Pour Soi couldnt have been any more disappointing in the Tingle Creek Chase on Saturday with the odds-on favourite's tanks emptying approaching the last at Sandown.
Planet Sport Bet have subsequently lengthened the Susannah Ricci owned nine-year-old to 10/1 from 11/2 for the Queen Mother Champion Chase at the Cheltenham Festival 2022.
"Chacun Pour Soi was very disappointing," Mullins said at Punchestown on Sunday.
"He's very sore behind today. We are not sure what it is yet, but we said we'd give him another day to get over it as he only arrived in this morning."
Elswhere, Dan Skelton's Nube Negra has been pushed out to 14/1 from 8/1 for the Queen Mother after failing to land a glove on his Tingle Creek opponents.
Greaneteen leaves Champion Chase field feeling blue
Paul Nicholls sent a strong message to the prospective 2022 Queen Mother Champion Chase field that it is not a foregone conclusion for the market leaders.
The Ditcheat trainer recorded a one-two via the impressive Greaneteen and Hitman, with the former shaved to 7/1 from 12/1 by Planet Sport Bet for the Queen Mother Champion Chase in 2022.
Starting at 12-1, Bryony Frost and Greaneteen travelled handily through the two-mile Grade One contest until he was ridden to take up the lead over the penultimate fence.
From there he pulled further and further away from stablemate Hitman, and eventually crossed the line five and a half lengths ahead to give Nicholls a one-two in a race he was winning for the 12th time.
"He is improving enormously all the time. Today was the best I have ever seen him look. He is a young horse and he wasn't beaten far last year and we probably didn't ride him right.
"We didn't have enough belief in him to be honest, but he stays on really strongly now and you can ride him differently. He was beaten two lengths in the race last year and I know he has improved more than that.
"He is a real live contender for that (Champion Chase) and obviously loves it around here, but obviously the Champion Chase will be his target now." said Nicholls on Greaneteen.
Energumene brings the energy at Cork
There was better news for Mullins with unbeaten Energumene registering a facile eight and a half length win in the Kerry Group Hilly Way Chase at Cork on Sunday.
The seven-year-old enjoyed a faultless novice campaign over fences last term, claiming Grade One wins at Leopardstown and Punchestown either side of missing the Arkle at Cheltenham due to a minor setback.
Energumene was sent off the 1-3 favourite to make a successful reappearance in a Grade Two contest his trainer Willie Mullins has dominated over the years and ultimately did so without much fuss.
Travelling strongly and jumping soundly at the head of affairs under Sean O'Keeffe, the son of Denham Red comfortably drew eight and a half lengths clear of Daly Tiger, with Sizing Pottsie third.
Planet Sport Bet have snipped Energumene into 5/2 for the 2022 Queen Mother Champion Chase behind Nicky Henderson's 7/4 favourite Shishkin.
Mullins' assistant, David Casey, said: "Sean said they went very quick early and he was happy when he went to the front, but the other horse (Notebook) took him on down the back straight and they ended up racing.
"Other than that, he'd have been very impressive and his class told in the straight and he won easily.
Kilcruit drifts after 1/12 Cork turnover
Chacun Pour Soi wasn't the only upset for Willie Mullins over the weekend with top class bumper winner Kilcruit suffering a shock defeat on his hurdling debut at Cork.
The Willie Mullins-trained six-year-old won at the Dublin Racing Festival and the Punchestown Festival last season, as well as filling the runner-up spot behind stablemate Sir Gerhard in the Champion Bumper at Cheltenham.
Subsequently, the Stowaway gelding was a prohibitively priced 1-14 favourite to make a successful reappearance in division one of the Follow Us On Instagram Maiden Hurdle.
But having raced alongside Henry de Bromhead's Largy Debut for much of the way, Kilcruit was ultimately left trailing in the 6-1 shot's wake, with 10 lengths separating them at the line.
Planet Sport Bet have relaxed Kilcruit to 10/1 from 4/1 for the Supreme Novices' Hurdle as a result.
Mullins' assistant, David Casey, said: "Sean (O'Keeffe, jockey) said he didn't travel through the race and was beaten early. We have no other excuse than that at the moment anyway.
"He said he jumped well but then was flat at the third-last and that's why he was missing them. We'll have a look and see."
