Scrum-half Natasha Hunt has returned to the England squad for Saturday's rematch against France at Twickenham.
Loughborough's Abbie Brown, who can play at wing or full-back, is called up for the first time since her return to the 15-a-side game from sevens.
Hunt's Gloucester-Hartpury team-mate Ellena Perry is a new front-row option.
A strong second-half performance helped England to a 33-10 win over France in Grenoble last weekend.
"Last Saturday's game against France was a tough and physical affair and we expect more of the same," said head coach Simon Middleton.
"We've spoken a lot about resilience, which we've shown in our training and our two matches at the start of the season to date.
"While we were delighted with the result and much of the performance in France, we know we need to be better this weekend."
Hunt's return increases Middleton's options at nine after Claudia MacDonald and Leanne Riley played scrum-half in the wins over Italy and France respectively.
