Wales are sweating over the fitness of fly-half Dan Biggar ahead of their second Test match against Japan in Tokyo.
Biggar is one of a number of injury concerns for Wales after their narrow 22-18 victory in the first Test in Osaka last weekend.
An possible standby contender for the British and Irish Lions, Wales team manager Alan Phillips expects to know more on Biggar's condition on Thursday.
"We will know more about selection on Thursday because we still have a few guys with a few problems," said Phillips.
"Dan Biggar is not training because he has a tight hamstring. It's nothing to worry too much about but we're looking after him.
"We can't work the players too hard this week because it's the end of another long season. It's about looking after them for one final push, though we definitely expect them to play a lot better because it's their second game together."
Phillips also confirmed there would be no Television Match Official for the second Test as was the case in the first, when Wales were frustrated at being unable to overturn some decisions.
"As we understand, tier two rugby nations do not necessarily get TMOs for Test matches because there's a big cost factor involved to fly people out from, say, Australia or New Zealand, for a couple of weeks. It was surprising but that's the ruling," said Phillips.
"We're not worrying too much about it because it doesn't change much. There were opportunities that could have worked either way on Saturday, it's just the way it is.
"It's part of the experience when you come to a developing rugby country and perhaps that's good for us. You can get blase about the organisation back home in the Six Nations and other games so we have to deal with it and that's not necessarily a bad thing."
