Goalkeeper Mat Ryan will miss the Socceroos' friendly international against Kuwait next week, the first outing under new coach Graham Arnold.

The FFA says Ryan, the first choice gloveman at the last two World Cups, has been given the October FIFA window off to help manage an unspecified minor injury, also ruling him out of this week's training camp in the United Arab Emirates.

It opens the door for Ryan's 2018 World Cup deputies Danny Vukovic and Brad Jones or Mitchell Langerak to start in goal against Kuwait at the Al Kuwait Sports Club Stadium on Monday [Tuesday AEDT].

Ryan kept a clean sheet in Brighton and Hove Albion's 1-0 Premier League win over West Ham on Friday but Arnold said it was best for him not to make the trip.
