However, on Thursday the BOA chef de mission Andy Hunt said that an update could be expected soon on when Phillips was going into the “Games environment”.
“I do know where Phillips Idowu is. He’s improving his fitness,” Hunt said.
Van Commenee had said on Wednesday that he found it “bizarre” that GB were having “to deal with the situation” as it was presented to them.
He added: “First, he has to show up – and we don’t know when he will. When he shows up, where he sleeps, we have no idea.”
Idowu, world champion in 2009, is one of Britain’s big hopes for athletics gold, but he has not competed in two months and confusion has surrounded his fitness as the days have ticked away before London.
The participation of the 2008 silver medallist, external was called into doubt last week when he failed to attend a pre-Games training camp in Portugal.
This led to the BOA requesting medical records for a reported nerve problem in the 33-year-old’s hip and back, a decision which left Idowu “incredibly disappointed and surprised”, his agent said.
Hunt has already said he expects Idowu to be fit for London 2012, but Van Commenee continued: “It’s not good, obviously, because I know how important coaching is.
“That’s the reason we go on camp, so athletes have 24/7 support staff.
“Phillips decided not to join and in my eyes that compromises his preparation.
“We will support him when that is needed, as we always have. UK Athletics has supported Phillips Idowu for about 12 years. Financially, a big part for that 12 years in terms of providing training and accommodation, camps, medical support, psychological support, biomechanical support. We have paid the salary of his coach – our coach.
“I’m perplexed really that, in the last few weeks before the Games, he turns his back on us.”
Van Commenee and Idowu first fell out last summer when the latter pulled out of the European Team Championships. After a subsequent public row about Idowu’s use of Twitter, the two have not spoken since.
