The Saints travel to Wales to take on the Newport Gwent Dragons this weekend and Jim Mallinder’s troops are currently sitting pretty in their group with two wins from two.
And in a competition where sides generally give their younger guns a chance to fire, younger brother Ethan will be starting at loosehead prop.
And the 21-year-old admits he is relishing the chance to show the coaching staff and fans what he can do from the start, having been mostly restricted to cameos from the bench this season.
“The LV= Cup is always something we pick out, the guys who are maybe not starting or regularly in the matchday 23,” he said.
“This is our chance to lay down a marker, to prove that we can start games as opposed to coming off the bench.
“Rugby is a huge part of the culture in Wales and we know what a big test it is going to be for us,” he added.
“But that is a challenge we are looking forward to. We want to keep our good start going in this tournament.
“Two more wins and we could get a home semi-final which would be fantastic.”
For the Dragons it will be a case of trying to build on their victory last time out in the competition against London Wasps.
But after a disappointing Euroepan campaign came to its conclusion last weekend, Andrew Coombs has called on his teammates to learn their lessons ahead of the rest of the season.
“At the end of the day we are a very young squad and still learning,” he said.
“But we will come back better and stronger from these experiences, in whatever competition it is we are playing in.”
