Jonathan Davies is in doubt for Wales' semi-final clash with South Africa, however Wales are confident he will be fit for the clash after he suffered a knee injury.
Davies was set to start the quarter-final against France but pulled out of the team just before the game after taking a knock to his knee with 23-year-old Owen Watkin taking the veteran centre's place in the starting lineup.
Wales skills coach Neil Jenkins said the 85-cap player should be ready to take part in full contact this week and prove his fitness for the clash in Yokohama on Saturday.
"He seems OK. He is getting back to it, so I would like to think he is going to be taking a full part this week in training and obviously be fit for Sunday," Jenkins said.
"He is a key player for us, a big player, someone that we need fit, realistically. Owen did exceptionally well on Sunday and is a talented player, but the more numbers we have, the better."
"Jon trained most of the week last week but didn’t feel he was quite right. It’s an important game on Sunday and we need all hands on deck to get through that match. Jon is a world-class player and you need your world-class players fit and hopefully he will be available for selection. We will see how it goes this week."
Davies should start if he is fit, however if he is unable to face the Springboks, Watkin is likely to start alongside Hadleigh Parkes while Wales have also called up test rookie Owen Lane to replace injured loose forward Josh Navidi this week.
Lane received his World Cup from Prince Charles at Wales training on Wednesday.
