Wales have lost four members of their squad for the China Cup with Joe Ledley, Ethan Ampadu, Tom Lawrence and Neil Taylor having withdrawn.
New boss Ryan Giggs has called in Sunderland defender Adam Matthews.
Giggs was already without Arsenal midfielder Aaron Ramsey for his first games in charge.
The Football Association of Wales has given no reasons for the withdrawals of Ledley, Ampadu, Lawrence and Taylor, but they have recently been injured.
Wales face hosts China on Thursday, 22 March and either Uruguay or the Czech Republic on Monday, 26 March.
