Deep Cave takes a major step in his remarkable season at Doncaster on Saturday, targeting the Great Yorkshire Chase. The Christian Williams-trained horse has won his last two starts at Bangor and Ascot, showing a sharp aptitude for fences. A victory here would complete an impressive four-timer and serve as a key prep for his Grand National tilt in April.

The field is packed with quality. Grand Geste, trained by Sue Smith and Joel Parkinson, is the chief threat after an easy Tommy Whittle win. Last year's winner Docpickedme returns off just a 2lb higher mark, while Josh The Boss is intriguing stepped up to three miles. This Grade 2 contest is a serious test of credentials.

Elsewhere on the card, the Grade Two River Don Novices' Hurdle features a compelling clash between Carlenrig and Rocking Man. The Irish-trained Feet Of A Dancer heads the market for the Yorkshire Mares' Hurdle. Sky Sports Racing provides live coverage from 9.30am, with a special preview show offering expert insight.
