Paul Nolan admits Defy Logic has plenty on his plate as he aims to make it two from two over obstacles in Sunday's Novice Hurdle at Naas.

The six-year-old absolutely bolted up in a Fairyhouse bumper in late November and was similarly impressive when making every yard of the running on his hurdling bow at the same track earlier this month.

Tony McCoy will take the ride in this weekend's Grade Two contest and connections are likely to learn plenty about the gelding's potential spring targets.

Defy Logic does hold an entry in the Neptune Investment Management Novices' Hurdle at the Cheltenham Festival.

Nolan said: "It's a big step up in class for him and it will be interesting to see how he gets on.

"We know he's a big horse and a chaser in the making, so it's not all about Sunday, but having said that I'm hopeful he'll run very well.

"He'll probably want more of a trip in time but on this ground we're happy to stick to two miles and we'll see what happens.

"We're very fond of him and know what we think he is capable of, hopefully, in the future."

The horse that sets the standard is the Gordon Elliott-trained Don Cossack.

The three-time bumper winner has perhaps not reached the heights expected of him so far over hurdles this season, but was only narrowly beaten in a Grade Two at Punchestown last time.

Elliott said: "He is in great form and he has come out of Punchestown very well. We will keep him to two miles for the moment and he won't mind the soft ground.

"It looks a good race and we'd be hopeful of a big run from our lad."

Regarding a potential trip to Cheltenham, the trainer said: "He is in the Supreme and the Neptune, but we'll get Sunday out of the way first before we make any further plans for him."

Moscow Mannon is a fascinating contender for trainer Brian Hamilton.

Fourth in last season's Champion Bumper at Cheltenham, the seven-year-old made a fine start to his jumping career at Navan in early December but has been sidelined since.

Hamilton said: "Moscow Mannon will be using Sunday as a fact-finding mission.

"He is entered in Cheltenham but that might come a bit too soon. We will see how Sunday goes first."

Champion trainer Willie Mullins is represented by prolific mare Annie Power, who has yet to taste defeat in five career starts.

The seven-runner field is completed by Art Of Logistics, The Tullow Tank and Diplomat.
