The head coach of UK Athletics, Charles Van Commenee says he doesn't know if Phillips Idowu will be fit for the Olympics.
The triple jumper hasn't competed since picking up an injury in June and has not attended the Great Britain training camp in Portugal.
On Tuesday, Idowu's agent said the athlete was disappointed that the British Olympic Association made public a request to see his medical records.
Van Commenee says he's frustrated and admits there has been a breakdown in trust between the pair.
"He's not here - I wish he was here, because I think it is the best place to prepare" Van Commenee said. "His coach is here, the best medical staff are here and all the athletes are here, so I'm slightly frustrated with that.
"At the same time I feel sympathy as well because he is not in the greatest place two weeks before the most important moment in his athletic life and you would never wish that to any athlete"
"I have one sanction: I could withdraw his entry to the Games, obviously I'm not going to do that because I don't want to take that away from him nor from the crowd."
Sky has learned that Idowu has a trapped nerve behind his knee, something that was not disclosed when he was selected for the Games.
Idowu is due to compete at the Olympics on 7th August.
