The contrast between Britain's two brightest sprinting prospects could not have been more stark after the second day of the Olympic trials in Birmingham on Saturday.
While teenager Adam Gemili secured his place on the team for London by finishing second in the 100 metres final behind Dwain Chambers, fellow 18-year-old Jodie Williams left the track in tears.
Williams pulled up in agony around 15m from the line in the women's 100m final, having apparently suffered a season-ending hamstring injury.
The world junior champion will undergo a scan in London on Monday, but an initial assessment suggested a grade-two tear and Williams wrote on Twitter: "Thank you to everyone for the support, really means a lot. Absolutely gutted but I'll come back fighting next year."
Speaking after the semi-finals of the 100m, Williams had also said: "It's been my dream since I was five years old to compete in the Olympics. I would be gutted not to make it."
Williams, who has been described by UK Athletics head coach Charles van Commenee as "the sort of athlete every country is waiting for", won the world junior 100m title in Canada in 2010 and silver in the 200m.
But she admitted this week that she has been struggling with injury all year, while she only completed her final A-level exams on Thursday.
