Changes made to Grand National course

Mounting concerns over the safety of the Grand National have forced organisers to make modifications to the course following a review of the world’s most gruelling horse race. However, while there will be changes to fence design, landing areas and course irrigation, the size of the field will remain at 40 horses. Also, Becher’s Brook – the much-feared fence criticised for its severity – will keep the same drop and dimensions. Ten horses have died in the past 12 years of the National, sparking criticism from animal welfare groups. “Balancing the Grand National’s enduring appeal while working to reduce risk in the race is a delicate but important balance to strike,” said John Baker, who runs the Aintree course in Liverpool.

Chavez could lose fight purse over marijuana

Middleweight fighter Julio Cesar Chavez Jnr could be stripped of his US$3 million purse, depending on the explanation he offers to Nevada boxing regulators about a positive test for marijuana after his first professional loss last weekend in Las Vegas. Top Rank Inc spokesman Lee Samuels said promoter Bob Arum  was aware Chavez, 26, had tested positive for the drug. “Chavez will have the opportunity to explain the situation to the Nevada State Athletic Commission,” Samuels said.
