Wales manager Robert Page has been forced into two changes from Friday's defeat to Armenia.
Defender Ben Davies is not available after he withdrew from the squad to be at the birth of his first child, in his place starts Neco Williams.
The other change sees Joe Morrell come into the midfield in place of the suspended Kieffer Moore, so there will be a shuffle in formation without the target man up top for Wales.
Dan James and Brennan Johnson will be furthest forward, with Aaron Ramsey and Harry Wilson in support.
Morrell and Ethan Ampadu will form the base of midfield in front of a flat back four.
Wales: Ward, N Williams, Rodon, Mepham, Roberts, Ampadu, Morrell, Wilson, Ramsey (c), D James, Johnson

Hello and welcome
Turkey v Wales (19:45 BST)
Noswaith dda. Good evening and welcome to our live coverage of Wales' Euro 2024 qualifier against Turkey.
This is a big night for Wales and their manager Robert Page after they suffered an embarrassing 4-2 defeat at home to Armenia on Friday.
As a result, Wales can't really afford another defeat if they are to reach next year's tournament in Germany.
And what of Page's future if they lose again tonight? He'll be trying not to think about that.
It's a massive game for Wales so, without further ado, let's have a look at the teams.
