RACING: Bust Out, one of the main Irish hopes for the Arkle Trophy at Cheltenham, will miss the festival due to leg problems.

The Jessica Harrington trained horse, winner of the Arkle at Leopardstown last month, has had a recurrence of the leg trouble that kept him out for much of last season. Bust Out will also miss the rest of this season and could face up to 18 months on the sidelines.
