Toshack left to rue injuries from Estonia victory
Two worrying injuries to key players took the edge off Wales' encouraging 1-0 win over Estonia at Llanelli.
Wales fielded the youngest side in their history and it was their oldest player, Nottingham Forest's Robert Earnshaw, who scored the first-half winner from the penalty spot.
But injuries to key players Jack Collison and Ched Evans will need to be assessed by the Wales medical staff on Monday when the squad meets up again in London.
Boss John Toshack will then take his youthful party to Baku on Tuesday to prepare for next Saturday's World Cup qualifier with Azerbaijan.
Collison has suffered a slight recurrence of the knee injury that has kept him out for 10 weeks until his return for West Ham in the last two weeks of the season.
And Evans has a back muscle injury that forced him off in the final minutes.
Toshack said: "We do not think either of them are serious, but we will assess them both again when we meet up in London on Monday for the flight to Azerbaijan.''
Wales will train at Bisham Abbey on Monday and Tuesday before a late evening flight to Baku, with Toshack hoping Collison and Evans are fit enough to travel.
He said: "Many of our lads have been out of training for a few weeks now, and our lack of fitness showed in the second half. We certainly needed this run-out ahead of the World Cup game, it was important.
"Our fitness levels were not good, but it was nice to get a game in and to register a win.''
But Toshack accepts that the match in Baku will be an eye-opener for the youthful Wales squad.
He said: "It will be interesting to see how they cope because it will be a hostile place and very hot. I have never fielded such a young side as that, certainly not at club level. I would have gone out and bought half a dozen players by now.
"We will find a match that will be a good character builder for them all.''
Toshack gave three more teenagers their debuts against Estonia - Joe Allen, Andy King and Simon Church.
He said: "All three did well when they came on, and I was particularly pleased with Church who showed a lot of skill and effort in the 20 minutes he had.''
