FIFA has announced all yellow cards will be wiped for the European World Cup play-offs in March.
This means that players will not be banned from the final if they receive a yellow card in the semi-final matches.
Despite this, players who received two yellow cards in the qualifying stage will still be suspended from the semi-finals, as they are already banned.
The ruling will affect 107 players amongst the 12 teams in the play-offs – who were one card away from suspension.
Both Rob Page and Steve Clark had called for the rule change.
Welsh players who were originally one card away from suspension were;
Aaron Ramsey, Joe Allen, Kieffer Moore, Harry Wilson, James Lawrence, Chris Gunter and Sorba Thomas. They now face no threat of suspension from a single yellow card.
For Scotland – captain Andy Robertson, John McGinn, Che Adams, Billy Gilmour, Jack Hendry, Scott McTominay, Kevin Nisbet and Stephen O’Donnell are all cleared.
Wales host Austria at the Cardiff City Stadium on the 24th March in their play-off semi-final.
Scotland face Ukraine on the same night at Hampden Park.
If both Wales and Scotland win, they will meet for the ultimate World Cup play-off final in path A.
The finals take place on the 29th March, with three teams in total qualifying for the 2022 World Cup in Qatar.
Wales are 64 years without World Cup qualification, and have the chance to make history in March.
Three teams of 12 will qualify for the World Cup, with one winner proceeding per path.
In qualifying path B, Russia face Poland and Sweden battle Czech Republic.
The final qualifying path C sees Italy take on North Macedonia, and Portugal host Turkey.
This means that either Cristiano Ronaldo’s Portugal or Euro champions Italy will miss the World Cup, as only one proceeds.
