WORCESTER'S Ceri Large, Bianca Blackburn and Laura Keates start for England women in tomorrow's Rugby Super Series opener against the USA at Calgary Rugby Park (11pm BST).

Lichfield’s Sarah Hunter will captain a young side that includes two players in Worcester's Lark Davies and Rachel Lund, who could make their England debuts if called off the bench.

Blackburn gets the chance to get more caps under her belt after making her first national start in this season’s Six Nations.

At the other end of the scale, Worcester's Rochelle Clark will become England women’s most capped player of all time with 101 caps if she comes off the bench.

Head coach Simon Middleton said: “Given the tight turnaround of games in this tournament and the fact that several of the players were involved in the Rugby Europe Sevens Grand Prix this month, squad rotation is going to be key.

"This is a really intense tournament against world-class opposition so we need to ensure the players are fit and ready for each Test.

“For this game, Sarah’s experience will be invaluable in leading the team, while I am really excited to see how Emily Scott goes at fly-half and Ceri at centre.

"We have two new caps on the bench, who I know have the potential to make a real impression, while Rochelle will relish getting the chance to secure 101 caps.

“We haven’t played the USA for some time but we know they will bring a lot of physicality, pace, energy and enthusiasm. This is going to be a tough opening Test match.”
