Philadelphia Union have recalled goalkeeper Rais M'Bolhi from his month-long sabbatical.

The Algeria international was sent away by the Union in early April, returning to his home in France, after seemingly being surplus to requirements.

However, M'Bolhi remained on the Union roster and is now back in Philly following injuries to fellow glovemen John McCarthy and Andre Blake.

Union boss Jim Curtin admitted he had not seen a massive change in former Marseille and CSKA Sofia man M'Bolhi since his return but acknowledged that the 41-time Algeria custodian was still part of Philly's playing group.

"It's only been two training sessions, so I can't say I've seen anything different," Curtin said.

"We have two injured goalkeepers and he's our third under contract. We still will explore what the best option is to give us a chance to get a result in Vancouver (against the Whitecaps this weekend).

"He is a Philadelphia Union player still," Curtin added. "That part never changed. There have been teams that have inquired about him in the future. The windows aren't open right now. We'll always listen and explore but he is a Union player first and foremost."
