The jockey will be armed with the results of independent medical examinations that support his case.n The retired trainer Sue Armytage has died from cancer. Mrs Armytage, who was in her sixties, assisted her former husband, Roddy, in his training operation and branched out in her own right when they separated. She had called the racecourse to be told he had been taken to the Queen's Medical Centre in Nottingham but by the time she arrived Davis had died. His funeral will be held at Earl's Croome Church, near Worcester, at noon on Friday.n Walter Swinburn visits the Jockey Club today seeking approval for his return to race-riding after a five-month absence due to injuries suffered in a fall that almost claimed his life in Hong Kong. Richard Davis, the jockey crushed in a fall at Southwell on Friday, died from a lacerated liver and uncontrollable internal bleeding, it was announced yesterday by the Nottinghamshire coroner, Dr Nigel Chapman.

Yesterday's opening of the inquest in Newark into Davis's death was adjourned for further investigation. Lammtarra's generation should triumph on Saturday.INDEPENDENT RATINGS FORSATURDAY'S KING GEORGE124 Pentire, 122 Luso, 121 Classic Cliche, Swain, 119 Singspiel, Strategic Choice, 117 Oscar Schindler, Shaamit, 116 Annus Mirabilis, 114 Farasan, 112 Song Of Tara.. It was attended by Davis's mother, Ann, who said she had watched her 26-year-old son's fall on television in Flavell, Worcestershire. In terms of comparitive form and times this seems excessive - 117 would be nearer the mark.Even on the optimistic view, Shaamit has nothing to spare against battle- hardened adversaries in Classic Cliche and Pentire.

Both have trodden an injury-strewn path and done their growing-up in public.But Lammtarra came into the Derby with far better form than Shaamit's, having won a Listed race from the Group-class filly Myself in an exceptional debut time. William Haggas's colt, by contrast, beat ordinary horses for his maiden win and has yet to put up a fast time.The official handicapper's assessment of Shaamit's Derby win, a rating of 123, is on a par with that accorded to Lammtarra at the same stage. In 1977, the Derby contestants had yielded just one win from 21 subsequent efforts before The Minstrel's stirring King George victory - that of The Ministrel himself in the Irish Derby.It is in comparison with last year's Derby winner, the great Lammtarra, that Shaamit's King George chances are best assessed. That quality can appear somewhat strained, however, in the immediate muddle of the Derby form itself. This year, only one victor, Chief Contender, has emerged from 12 subsequent efforts by Shaamit's victims at Epsom last month. But that is par for Derby fields. By the time of the King George, the corresponding strike-rate for the previous three years was two from 12, two from 24 and nought from six. "There's been two gold medals for Ireland already," Prendergast said yesterday, "let's hope we can get the third.".
