Scott Williams is aiming to be fighting fit for next season.
Wales centre Scott Williams is 'gutted' not to be heading to South Africa this summer as he continues to struggle with a shoulder injury.
Williams picked up the problem in Wales' RBS 6 Nations clash with Ireland in Dublin in February and hasn't played since.
The 23-year-old, who started the opening two rounds of the 6 Nations alongside Jamie Roberts, had hoped to return in time for the final round of the RaboDirect PRO12 campaign but fell short of that target as he watched his Scarlets side beat Cardiff Blues on Saturday night.
The injury means Williams won't be available for the Probables versus Possibles trial at the Liberty Stadium on Friday, May 30, or for the two-Test series with the Springboks and the mid-week clash with the Southern Kings next month.
"I wanted to play against the Blues but in the middle of my recovery I had a week where the injury niggled a bit and I couldn't do much, so that set me back," said Williams, who hasn't worn Scarlets colours for four months.
"After that, we decided to leave it for the season and make sure it is 100 per cent for next season in readiness for a big year with the World Cup coming up.
"I am gutted that I am not going to be available, but it is best to make sure it is 100 percent right.
"I had an operation on my other shoulder at the end of last season and it did help me having a full pre-season. I felt I had the best season I have had so far up until the injury."
Wales defence coach Shaun Edwards has confirmed that Williams won't be touring as a result of his shoulder worries but he dismissed any suggestions that the midfielder was being rested.
"Scott's not being rested - he's injured, that's why he's not going. The build up for the Rugby World Cup starts here. It's not a matter of resting him - I don't think there's many people being rested."
As the countdown continues for RWC2015, Tournament Chief Executive Debbie Jevans visited the Millennium Stadium to discuss preparations for the eight matches and reveal the positive news that 100,000 tickets for games at the home of Welsh rugby have sold in the last seven days.
Jason Harries is targeting a first win on the World Series circuit this season with Wales. The series returns to action this weekend in Dubai where Harries is part of a team hoping to build from its efforts in round one in October.
Wales skipper Jevon Groves says his side have addressed a few points from Gold Coast and aim to 'hit the ground running' in the next two rounds of the World Series, kicking off with this weekend in Dubai before heading off to South Africa next week.
Wales Sevens manager Steff Thomas is hopeful his side can build from a quarter-final spot in the opening round of the World Series in Australia when his side take part in the forthcoming double header in Dubai and South Africa.
