Adam Gemili records first sub-10 second 100m at Diamond League meeting in Birmingham

Adam Gemili became only the sixth British athlete to post a sub-10 second 100m at the Sainsbury's Birmingham Grand Prix on 7 June, but his joy at such an achievement was cut short by a worrying injury.

The 21-year-old, who collected two silver medals at the Commonwealth Games in Glasgow last year, clocked an impressive personal best of 9.97sec to finish second behind American Marvin Bracy, but appeared to fall as he crossed the line before receiving assistance for a hamstring problem.

Former budding footballer Gemili now has the distinction of being the very first Briton to run under 10 seconds in the 100m having previously finished the 200m in under 20sec.

Elsewhere on a busy day at Alexander Stadium, 2012 Olympic champion Greg Rutherford triumphed in the men's long jump competition after recording the second longest leap of his career at 8.35m.

Dina Asher-Smith, fresh from her record-breaking performance at the at the AA Drink FBK Games in Hengelo in May, recorded a personal best of 22.30 to finish third in the women's 200m behind Jeneba Tarmoh and Allyson Felix.

Jessica Ennis-Hill did not compete at the event as part of an attempt to preserve her fitness in the aftermath of reaching the qualifying standard for Rio 2016 at the Hypo Meeting in Gotzis, while Mo Farah also pulled out claiming to be 'emotionally and physically drained' following a difficult week involving allegations made against coach Alberto Salazar.

Christine Ohuruogu was withdrawn due to concerns over a hip issue.
