Worcester's Jo Yapp continues her captaincy of the England Women's side for this weekend's clash with Scotland at Murrayfield.
The scrum-half leads a side looking to add to Champion-ship wins over Wales and Spain. The only change to the line up that routed the Spaniards 86-3 earlier this month is replacement of Lichfield's Charlotte Barras with Henley centre Danielle Waterman. Worcester's Nicola Crawford continues on the wing.
England will be in for a severe test against Scotland who ran them close at Twickenham last season when it took Yapp's 71st-minute try to seal a 22-10 win.
Meanwhile Yapp's Sixways team-mate Claire Allan will start her first England A game this Saturday when Amanda Bennett's side take on the Nomads at Henley RFC.
Allan, who is not even a member of the England Elite 44 squad, has worked her way up from the England Women's Students team.
The 20-year-old full-back will make her first start after twice appearing on the bench this season. She takes over in the No 15 jersey from Saracens' Vicky Massarella, who will play for the full side at Murrayfield.
