The odds have drifted out from 25/1 to 40/1 in places since the news.
Bryony Frost has seen her odds on winning Sports Personality of the Year drift considerably, from 25/1 to 40/1, following the news that she will miss next month’s Grand National through injury.
Having broken her collarbone in a fall at Southwell on Monday, the jockey is now set to miss out on competing in her second Grand National, after finishing an impressive fifth on Milansbar last year.
Frost, from Buckfastleigh, made history at the Cheltenham Festival after becoming the first female jockey to ride a Grade One winner over jumps at the Festival.
The 23-year-old rode her beloved Frodon to victory in the Ryanair Chase, leading to bookies slashing odds on her winning the Sports Personality of the Year award from 100/1 as far as 20/1.
Anthony Joshua and Dina Asher-Smith lead the top of the market as 10/1 and 11/1 favourites respectively.
Frost would be the first female to win the award since 2006, but being ruled out of the high-profile race at Aintree leaves her chances looking even slimmer.
Oddschecker spokesperson George Elek: “The highs and lows of a jockey are clear for all to see with Bryony Frost, the star of the Cheltenham Festival, having been ruled out of Aintree next month.
“Whilst this may harm her chances of SPOTY this year, there is no doubt that we will be seeing much more of her in years to come.”
