Interesting times lie ahead at Cheltenham.
One of the big favourites, Cue Card, has been withdrawn after suffering a small muscle injury. They gave him a week to see how he recovered and there was no improvement, so he's getting a rest. Hopefully we'll see him back in action for the National meeting in April.
2013 Champion Chase winner Sprinter Sacre has also been withdrawn, after pulling up at Kempton with a heart related issue.
Trainer Nicky Henderson believes the horse is still missing 10% and that, although that might still leave him with enough to win, they would do better to focus on restoring him to full strength.
The Cheltenham authorities also face a tough decision over current third favourite for the Gold Cup, Last Instalment.
His trainer, Phillip Fenton, faces a court hearing in March, just six days after the Cup, charged with possessing banned substances including anabolic steriods.
The British Horseracing Authority has carried out dope tests on all horses at the stable, and if the results are clear the Cheltenham authorities then have to decide whether to let Last Instalment run.
There are two nightmare scenarios for racing. One is for Fenton to win the Gold Cup, only to be convicted of doping offences six days later.
The other is to force a great horse to sit out one of the highlights of the year only for the trainer to be found innocent.
It's not a decision we'd want to make, and it's not one they'll take lightly. But rest assured we at Bonus Betting will be on top of the stories throughout the Cheltenham Festival, as we bring you the best betting bargains we can find!
