The Worlds End could tackle the Doom Bar Sefton Novices' Hurdle at Aintree on Friday if he pleases trainer Tom George in his next schooling session.The six-year-old saw his chances of Cheltenham Festival glory dashed after coming down at the second-last in the Albert Bartlett when still holding every chance. "He just came alight and then came down. He was travelling very well and it looked like he was going to play a big part," said George. "He has had a nasty fall but, touch wood, he has had two schooling sessions since then and he has been fine. "We've got Perth but he is also in the three-mile novice at Aintree on Friday. He seems fine and if he schools well this week, there is no reason why he won't go there."
