Scotland's preparations for their clash with Samoa on Saturday have been hit by a late injury scare surrounding Nick De Luca.
The centre, who had an outstanding game in Fiji, became a late worry when he failed to finish the final training session before the game at Apia Park, Samoa.
"There is a slight injury concern about him," said Andy Robinson, the head coach, after the session. "He has a slightly strained thigh but we will wait until morning before making a decision.
"Joe Ansbro will come in if he is not fit."
There are no other worries, meaning that flanker Al Strokosch and prop Euan Murray, who had been concerns earlier in the week after injuring a calf muscle and knee respectively, both came through without any further alarm and will take their places in the team as scheduled.
In fact, Robinson pronounced himself satisfied with the final rehearsal before the big game, with Scotland shooting for a clean sweep of their Southern Hemisphere tour against a formidable looking Samoa side who have recalled all their big guns from leading European clubs for the occasion.
"I was pleased, I have seen the leadership really improve on the tour," the Scotland coach said. "There is clarity in the way they are trying to play and a great attitude, which is what you want going into a Test match.
"I just go Test by Test and I look forward to this one as much as I have looked forward to every one of this year.
"The key for us is to get ourselves into a winning position and then finish the team off. In the World Cup we got into winning positions and did not do that; at the start of the Six Nations, it was the same.
"This trip we have got ourselves into winning positions and have been able to finish the teams off. We need to do that again."
Robinson admits he has been impressed by a Samoan side which shows five changes from the one that clinched the Pacific Nations Cup by beating Japan last weekend.
With players such as Census Johnston, the giant Toulouse prop, and Tusi Pisi, the Wellington playmaker, returning to the team they are even stronger than the one that won the Pacific title.
"There are a lot of players who are playing in Europe, there are some outstanding talents, some young talent as well as some of the old heads like Johnston," Robinson added.
"They are a physical pack and those people who have not seen Maurie Fa'asavalu play for Harlequins are in for a treat. He is a big hitter and a strong runner.
"The other thing that I look at is the half-backs, the nine and 10, [Kahn Fotualii and Pisi], who are both quality players. So it is going to be a really tough Test match for us, but all the boys have real belief in what we are about."
Scotland will face likely 30-degree temperatures in the tropical sun, meaning the game will be a test of their stamina in the heat as much as their rugby prowess.
