Luke Chateris and Jamie Roberts are injury doubts for Wales's World Cup semi-final against France next Saturday.
Roberts is thought to have suffered a broken nose during his side's 22-10 quarter-final win against Ireland, while Chateris was withdrawn with a shoulder injury.
"It's just 24 hours just to assess him and hopefully it's not too serious," coach Warren Gatland said of Chateris.
The last time Wales reached the last four of the competition was in 1987.
