Wales' squad announcement and injury updates

Wales is set to announce their squad for the quarterfinal match against Argentina. There are fitness concerns regarding Gareth Anscombe and Liam Williams. Anscombe's groin injury makes it unlikely for him to be in the 23-man squad, while Williams' knee injury has put his availability in doubt. If Williams cannot play, the options for fullback include Lewis Rees-Zammit or Lee Halfpenny. In the back row, Aaron Wainwright is expected to move to number eight to fill the absence of Touloupe Falatau. The options to replace Falatau at blindside flanker are either two opensides, Jack Morgan and Tommy Reffel, or a more physical option with Dan Lydiate or Chris Chantsler. Dewi Lake may retain his spot at hooker, given his solid performances in the lineout.
