Goalkeeper Wayne Hennessey was finally back in training for Wales on Wednesday to give himself a fighting chance of being in the side to face Liechtenstein at the Millennium Stadium on Saturday.
The young Wolves keeper had spent two days in bed recovering from a stomach bug at the team hotel as the team prepare for the World Cup qualifier, but if Hennessey does not face Liechtenstein, boss John Toshack has Hull's Boaz Myhill as an alternative.
Wales goalkeeping coach Paul Jones said: "Boaz has done well and Hull have made a great start to the season. He is a chirpy lad and we probably needed a little more of that with so many youngsters in the squad."
He added: "We did not have that much competition in goal. But Tosh wanted to have two guys pushing for each spot.
"Wayne has done the job for us and you cannot dispute that and Boaz has done very well at Hull. It is very close between them now."
The illness came just at the wrong time for Anglesey-born Hennessey, who is aiming to bounce back from being dropped by Wolves last weekend.
Wolves boss Mick McCarthy believed Hennessey needed a rest, but Jones added: "He was dropped and that surprised me. He was disappointed and that is great because that is the reaction what you want.
"He had made a mistake against Reading the week before but he still had a decent game by all accounts, but Mick made the decision. It is an experience he will have again, unfortunately, but he will bounce back.
"It does happen to a keeper because there is only one spot. I have told him to do his job, enjoy training and look forward to the game on Saturday.
"But I accept that he has played a lot, which is draining more mentally than physically. But he is looking fine."
