Alex Goode will take banned fly-half Owen Farrell's place in the starting line-up for Saracens' Heineken Champions Cup game against Lyon.
England captain Farrell has been banned for four weeks for a dangerous tackle.
Elliot Daly fills in for Goode at full-back, with Ivan van Zyl at scrum-half, Sean Maitland on the wing and Nick Tompkins starting at 12 on Saturday.
Three-time champions Saracens are third in Pool A after two wins from two, while Lyon are 10th.
That means the French side - who Saracens beat 28-20 when they travelled to France - are outside the qualification places currently.
The top eight teams from each of the two pools advance to the last 16 after four rounds of group games.
