Henderson wary of ground for Sprinter Sacre Nicky Henderson is anticipating a "sleepless night" ahead of Sprinter Sacre's planned return to action in the Shloer Chase at Cheltenham tomorrow. The former two-mile king is out to get back to winning ways for the first time since April 2013, but rain at the Prestbury Park venue on Saturday and the potential for more means his participation is in the balance. Henderson said: "I'd have been very, very hopeful on good ground, but tomorrow is now a worry. "We've had a little meeting and are going to sleep on it. I'm dying to run him and he needs a run. "We'll do everything we can to run, we'll just have to keep an eye on it. "Simon Claisse (clerk of the course) says he is going to be here at 4.30am and I'll be ringing him as I think we are all going to have a sleepless night."
