Manchester City have admitted that a breakdown in communication was behind Craig Bellamy's no-show for international duty with Wales.
The international captain was due to report for duty with John Toshack's squad on Sunday evening but did not appear at the team hotel.
He missed Monday's flight out to Montenegro for a midweek friendly and City have now released a statement revealing they were at fault for not contacting the Football Association of Wales to inform them that Bellamy aggravated a knee injury during Saturday's friendly win over Celtic.
"Craig Bellamy is continuing his fitness and rehabilitation work following a knee injury," read the statement.
"He suffered a reaction following Saturday's game against Celtic and is therefore unavailable to represent Wales in this week's friendly against Montenegro.
"Craig's situation should have been communicated to the Football Association of Wales over the weekend, but a misunderstanding on the process meant this was regrettably not done until today.
"Manchester City have now made contact with the Football Association of Wales to clarify the situation."
