Danny Gabbidon has been promoted from the Welsh under-21 side

It is part of their preparations for their World Cup group match on June 7 against England in Sapporo, Japan's indoor stadium.

Gabbidon and Earnshaw had been called into a Wales training camp at the Vale of Glamorgan Hotel near Cardiff, already arranged for next weekend.

That squad has now been transformed into a full international party, and the two, who figured in Cardiff's FA Cup giant-killing of Leeds, will be released for City's game with Brentford on Tuesday before joining up with the rest of the squad.

Both are products of last season's Wales Under-21 side, and the nearest either have previously got to a senior match was when Gabbidon was an unused substitute for the last international in Cardiff when Wales beat Belarus 1-0 in October.

Johnson recalled

Manager Hughes has lost Leicester midfielder Matthew Jones, who will miss the rest of the year with a knee injury, while they are awaiting a fitness check on Norwich's Iwan Roberts.

West Brom's Andy Johnson has earned a recall, but Huddersfield defender Steve Jenkins will be released to play in his side's Division Two clash against Blackpool - though he will remain on stand-by.

Premiership stars Ryan Giggs, Craig Bellamy, Gary Speed and Robie Savage have all been included, while John Hartson is certain to relish a battle with Argentinian strongman Roberto Ayala.

Football Association of Wales officials are hoping to put match tickets on sale on Wednesday at all their usual outlets.
