Spirit Son suffers another setback Spirit Son's participation in the Stan James Champion Hurdle at the Cheltenham Festival is in serious doubt after Nicky Henderson's six-year-old suffered another setback. The highly-rated hurdler has not been seen since winning a Grade 2 at Aintree last April, and is unlikely to return for the foreseeable future. Henderson said he could even miss the rest of the season saying, "The picture is grey. If you are going to miss two weeks at this point of the game, you are really out of the ball park. "We had a hiccup with him earlier on (in the season) which cost me three weeks, but this was a new problem. I'd rather start next season with a horse in one piece piece than risk him and lose him for this season and next." Henderson added: "Everything went great in his gallop the other day but Barry thought that he needed it and we ruled out Ireland (Irish Champion Hurdle). But we do have a problem and we will have to monitor it. "When you have a problem with a good horse it's all over the world before you know it owing to the exchanges. The work was great, but I fear we've got to take things very carefully."
