Henderson on edge for Sacre’s comeback

The nine-year-old has so far carried all before him over fences, winning 10 of his 11 starts, including an unforgettable triumph in the 2013 Queen Mother Champion Chase at the Cheltenham Festival.
But just when Sprinter Sacre was beginning to appear unbeatable, he was pulled in the Desert Orchid Chase at Kempton in December 2013, when he was found to be suffering with a heart problem.
