Nottingham Forest defender Neco Williams will miss Wales’ World Cup qualifier against Belgium on Monday.
Williams, 24, was substituted 21 minutes into Wales’ 3-0 win over Liechtenstein.
The former Liverpool full-back went down in agony after attempting a cross in a one-sided opening at Cardiff City Stadium, leaving the pitch on a stretcher following treatment.
“Give us a few hours. You just don’t know. We’ll find out tomorrow morning,” said Wales head coach Craig Bellamy after the match.
“The medical staff will be racing with it and make sure he’s looked after, of course. We’ll find out a lot more tomorrow.”
On Sunday morning, the Football Association of Wales confirmed Williams was not part of the travelling party for Wales’ qualifier with Belgium.
They also announced Cardiff City centre-back Dylan Lawlor has been called up for the fixture at the King Baudouin Stadium.
Lawlor, 19, made his senior debut for Cardiff in a 2-0 FA Cup loss to Aston Villa in February and was handed his league bow in the Bluebirds’ 4-2 defeat by Norwich City on the final day of the 2024-25 Championship season on 3 May.
He was part of the 29-man senior training camp under Bellamy in Cardiff and Alicante last month.
