Thursday's racing bulletin

The Five Live selection is Red Dahlia in the 1515 at Taunton (all times BST).

Shamardal, a leading contender for next season's 2000 Guineas and probable favourite for Saturday's Dewhurst stakes, will not be running in the colours of Abdulla Buhaleeba.

The colt, along with five others, has changed ownership and will now run for Gainsborough Stud.

Thursday's racing takes place at Newmarket, Worcester and Taunton.

Heavy rain across the country is likely to change conditions as the day progresses. Newmarket had 4mm of rain overnight and the ground has changed to good to soft with good places.

That description is likely to change because it is still raining. The prospect of soft ground will dramatically change the way the races are run and which means normal form lines can be discarded.

Frankie Dettori, now 16 clear of Kieren Fallon in the jockeys' championship, has six rides.

His best chances are Sundrop in the 1450 and Pearl Grey in the 1600.

Taunton had 9mm of rain last night and the going has eased to firm with good to firm places on the chase course.

Still a maiden, Red Dahlia in the 1515 will not find an easier option.

Mark Pitman's horses have been running really well recently and this mare was travelling well at Hereford when she cannoned into another runner, unseating her jockey.

It was a dry night at Worcester and the going remains good with good to soft places on the chase course.

Jack Pot in the 1500 is having his first run for Matt Shepherd but is expected to go well.
