Sheffield United trio Gary Naysmith, David Carney and Stephen Quinn will all be on international duty later this month.

Defender Naysmith will join up with Walter Smith's training squad ahead of Scotland's friendly against the Czech Republic in Prague on May 30 and Quinn will be part of Don Givens' Republic of Ireland Under-21 squad taking part in the Intercontinental Cup in Malaysia.

Australia international Carney faces a hectic schedule, starting with his country's friendly with Ghana in Sydney on May 23.

The Socceroos will use this as a warm-up game in preparation for World Cup qualifiers against Iraq (twice), Qatar and China in June.
