The handicap hurdle for conditional jockeys at Newbury on Friday was won by Our Dot's Baby, whose rider Page Fuller was handed a four-day ban by stewards after an animated post-race incident involving Lorcan Williams, who finished down the field on Confirmation Bias.
Williams, also suspended for four days, declined to comment on the dispute when contacted by the Racing Post, but appeared to be angered when Fuller eased her mount into contention before the turn for home, which led to Confirmation Bias becoming slightly unbalanced.
The Racing TV cameras picked up on the episode, which the stewards described as a "verbal altercation" and one worthy of punishment that will leave both jockeys on the sidelines from March 20-23.
Fuller, who reasoned the better ground had helped Our Dot's Baby, could not be contacted following the race.
Nicholls backing Cobden for title
Paul Nicholls knows all about being champion trainer and could soon be plotting how to make his stable jockey Harry Cobden a title-holder after a double for the pair.
Cobden began the day level on 100 winners with Harry Skelton, but nine adrift of reigning champion Brian Hughes.
The rider went about changing that by steering Paul Vogt's Siroco Jo and Sonny Crockett, who runs in the distinctive colours of Malcolm Denmark, to victory.
"Of course we'll help him," said Nicholls. "The title race will change every day and I keep telling Harry that we'll keep doing what we're doing and, after the Grand National meeting at Aintree in April, if we've got a serious chance, then we'll really kick for it.
"You can't just be running horses for the sake of trying to win it though. If our horses stay in form, he's got an outside chance."
Nicholls, soon to be a 12-time champion himself, added: "One thing we will do is have a lot of runners at Aintree and we'll keep plenty to go to Ayr's big meeting as well and Sandown on the final day of the season.
"I was going through the programme book last night and could find something for nearly every race at Aintree."
