Meanwhile a "slight injury concern" to David Humphreys, has forced Mark McCall to throw up a load of combinations in his backline rather than name a side as required by the competition rulers. Humphreys we are told will undergo a fitness test on Friday afternoon before taking his place in the side.
We are also led to believe that Simon Best is another injury concern and apparently will also undergo a late fitness test, if he is not declared fit then Declan Fitzpatrick will be brought onto the replacements bench. Ireland scrum half Isaac Boss returns from injury to start at scrum half.
