Chelsea have confirmed that defender William Gallas will not join the club on their pre-season tour of the USA.
Gallas' contract runs out in 2007 and he has not signed a new one
Gallas was supposed to report back to their training camp in Los Angeles on Monday but failed to turn up.
"He did not report and further action will now be considered by the club as a consequence," read a Chelsea statement.
His agent, Pierre Frelot, told BBC Sport that Gallas, 28, was delayed for personal reasons and that talks over his future will be held with Chelsea.
Gallas told the Blues in May that he wanted to leave - amid reports that he was unhappy at playing at full-back instead of his preferred centre-back.
His current contract runs out in 2007 and he has yet to sign a new one.
The Chelsea statement added: "Gallas was due to join the team with the other Chelsea players who participated in the World Cup semi-finals and final.
"William requested extra time off following the World Cup but was informed he should still report to Los Angeles on the date previously agreed with him.
"Pre-season training and the tour is about building team spirit among our squad and extra leave is only granted for valid football-related reasons.
"Discussions between Chelsea and William about a new contract are already well documented and ongoing. He has one year left on his current contract."
Gallas, who has been linked with Italian side AC Milan, is expected to return to London on Friday from his holiday in Guadeloupe.
The France international has been offered a new four-year contract and Chelsea have said they are not willing to sell him.
Gallas, a £6m signing from Marseille, has made more than 200 appearances for Chelsea in five years.
