Frankel's little brother Noble Mission goes on trial for the Investec Derby in the poptelecom.co.uk Fairway Stakes at Newmarket on Saturday.
He is most famous for the exploits of his elder sibling, although having won two of his three starts to date he is shaping up into a nice type himself.
Noble Mission is 33-1 for the Epsom Classic with Ladbrokes but as low as 14s with Betfred, and a victory in this Listed event for Sir Henry Cecil's colt would make him a viable outsider to the red-hot favourite Camelot.
"We had the option of coming for the Dante but Henry thought it would be more sensible to take things cautiously and not overdo him at this stage of this season," said Teddy Grimthorpe, owner Khalid Abdullah's racing manager.
"He's in good form and we'll see how he gets on this weekend before we make any plans.
"He obviously has the option of the Derby and also the King Edward VII Stakes at Royal Ascot."
John Gosden is thinking more in terms of the St Leger for Thought Worthy, who ran a nice race when second to Aidan O'Brien's Imperial Monarch in the Sandown Classic Trial.
"He's going to take on Henry's horse, Noble Mission, Frankel's brother," said Gosden.
"He ran a nice race at Sandown first time out but I was very impressed with the winner that day.
"Aidan's horse ran a lot further than we did and he finished the race off very strongly."
The most experienced horse in the field is Gerard Butler's Prince Alzain who has won two of his five races.
"He was declared to run in the Dee Stakes at Chester but he is a very correct, good-actioned horse and I didn't want to compromise his chances on the ground up there. We decided to wait for this race and I am very hopeful of a good run," said Butler.
"The plan was to run him in the UAE Derby but unfortunately he got an abscess in his foot, which scuppered that option. He didn't have the best of preparations going into the Lingfield race, so his run there was more than satisfactory.
"His sire Street Sense won the Kentucky Derby, while his mother won over a mile, so he is bred for this distance.
"We actually entered him in the US Triple Crown but we couldn't get enough runs into him because of his abscess.
"If everything goes well this weekend, we will look at running him in the King Edward VII Stakes or the Tercentenary Stakes at Royal Ascot."
