International Friendlies/Wales v England, Millennium Stadium, 2.30: England have arrived in Cardiff without all their star names as they embark on a three-game pre-World Cup schedule that also features back-to-back appointments with France.
But the team in action at the Millennium Stadium today are playing for potential World Cup places, which makes the game a huge encounter from manager Clive Woodward's perspective.
"It has been a good week, and there is a massive amount at stake tomorrow," said the head coach.
"We want to win this Test match, and the moment that is not at the forefront of your mind as a player or a coach you end up getting smacked.
"The side we have picked is extremely strong. I would put this team up against any team in the world and expect to win."
England will field two debutants - full back Dan Scarbrough and centre Stuart Abbott - against a full-strength Welsh side as Woodward runs the rule over many of his fringe World Cup candidates.
At outhalf, Wasps playmaker Alex King makes his first start, six years after winning his first England cap as a replacement against Argentina, and he would appear to be in a straight fight with Paul Grayson to provide back-up to Jonny Wilkinson.
The England selection has been termed a second XI in Wales, and there are many Welsh fans who expect to see their team record a first victory over England in Cardiff since 1993.
