Chris Coleman saw a Gareth Bale double give him his maiden victory as national team manager, though he will need to pull off another first in Osijek against a side who Wales have failed to beat in two previous meetings.
Former skipper Aaron Ramsey was booked against Craig Levein’s side so is suspended, with Dave Edwards having been called up in his place. Defender James Collins is still serving a ban after his red card against Belgium last month.
However there could be a return for defender Adam Matthews, who missed the win over Scotland with an ankle injury.
“Adam is with us and we’ll watch him carefully today and tomorrow,” Coleman said.
“We have to weigh up the consequences — he has not done a lot for two weeks, but he has improved since he has been with us and had more treatment.
“He could possibly join in tomorrow, or that might possibly be a little bit early.
“But he is with us and we will be waiting until the last minute before we say a definite yes or no.”
Coleman, whose side sit fourth in Group A — four points behind leaders Belgium — said his squad otherwise have a clean bill of health.
He said: “(Striker) Craig Davies is a little bit tight but he’s OK. We took it light with him today and he didn’t do too much, but he’ll be all right — he’s available for the game tomorrow. With everybody else, there are no problems.”
