CITY of York Athletics Club ace Richard Buck has missed out on a place in the individual 400 metres at the London 2012 Olympics.

Buck finished fifth in today's final at the Aviva 2012 Olympic Trials in Birmingham and will have to wait to see if he earns selection for the 4x400m relay squad.

Final winner Martyn Rooney and runner-up Conrad Williams will line-up for Great Britain at the Olympics.

Rooney clocked 45.93 seconds and Williams 45.97, with Buck timed at 46.68.
