THE British Horseracing Authority (BHA) has announced racing on UK shores will make a "risk-managed" return from an equine flu suspension tomorrow.

There had been a five-day suspension of all racing after a bout of influenza was last week reported by trainer Donald McCain at his yard.

High-profile trainers including Dorset's Colin Tizzard and Nigel Twiston-Davies were outspoken against the halt to racing.

In a statement, BHA's Chief Regulatory Officer, Brant Dunshea, said "robust containment measures" have been undertaken.

He said: "After analysis of thousands of samples, and no further positive tests on Monday, we still only have two confirmed sites of infection. We have put robust containment measures in place around both.

"From the testing and analysis conducted the disease appears to be contained at present.

"Clearly, there is some risk associated with returning to racing. This risk has been assessed and, based on the evidence - and ensuring biosecurity measures are in place – the level of risk is viewed as acceptable.”

Meetings at Musselburgh, Plumpton, Southwell and Kempton will go ahead tomorrow.

Meanwhile, Tizzard's Fox Norton could line-up in a high-class field for Saturday's Ascot Chase.

Tizzard's mount is firmly on the comeback trail after finishing a seven-length second to Altior on his first start after a long absence.

Last year's winner Waiting Patiently is one of nine horses in contention.

Ruth Jefferson's charge landed the Grade One event last term, but unseated his rider on his only subsequent start on his belated return in the King George at Kempton.

Paul Nicholls has two contenders in Cyrname, a wide-margin handicap winner at the track last time, and King George fourth Politologue.

Nicky Henderson has two contenders in Top Notch and Janika, while Grand National hope Abolitionist could represent Dr Richard Newland.

The Kim Bailey-trained Charbel and Venetia Williams' Aso complete the possible field.
