British triple jumper Phillips Idowu has been called to account over the injury which has clouded his Olympic Games build-up.

The 33-year-old Idowu, a silver medallist in Beijing in 2008, failed to travel to a pre-Games training camp in Portugal on Monday. That has led to the British Olympic Association (BOA) to ask him to explain why he missed the trip and to clarify the details of the injury.

BOA spokesman Darryl Seibel said: “Our chief medical officer Dr Ian McCurdie wrote to Phillips and his agent yesterday asking that he provide to Dr McCurdie the relevant medical records relating to his injury and the treatment he is currently receiving.”

“Those should be provided to our chief medical officer on a confidential basis. The basis for doing this is a clause in our team members’ agreement that says athletes are required to provide details of any injury or illness that may impact on their performance during the Games.”

Idowu is continuing to receive treatment on the hip injury that saw him pull out from this month’s London GP just before his event was due to start.

Idowu has not jumped competitively since a meeting in Oregon in the United States on June 1, when he took three jumps before sitting out the remainder of the meet.

He subsequently withdrew from meetings in Oslo and Paris and the UK trials in Birmingham.
