Luxembourg could be back riding out in 3 to 4 weeks Aidan O'Brien has given a positive update on Luxembourg who was ruled out of the Cazoo Derby due to a muscle injury. The Camelot colt was ante-post favourite for that Classic on the back of an unbeaten juvenile campaign culminating in a victory in the Group 1 Vertem Futurity Trophy Stakes at Doncaster in October, and a third place in the Qipco 2,000 Guineas at Newmarket last month. He has been on the sidelines since recently being found slightly lame on his off-hind but prospects are bright for an autumn campaign. O'Brien said: “He's fine and hopefully we'll have him back riding out in three to four weeks. He'll maybe start back long reigning. “It was up high lameness and that's hard to really diagnose so we think it was muscular. It's one of things, it's nothing major but he just needed the time. “John (Halley) and Ger (Kelly) just said he needed a month or six weeks in the box and then there was no decision. That was their assessment and it was an easy decision then after that. “It's very fickle training a horse, any athlete knows you are on a fine line and you are on the right side and wrong side the whole time. He just went on the wrong side. “He worked that morning, Seamus (Heffernan) rode him, and everything went well but just when he pulled out he started resting his hind leg. “The very odd time it can be a nerve and come right in 24 hours but obviously when the lads saw him it wasn't that and there was no decision to be made. “He's a very good horse, very natural, and will improve with the time. He's going to be exciting for the autumn so maybe it was a blessing in disguise and we'll know come the autumn.” Additional reporting by Gary Carson
