Davies has named a strong starting XV against Doncaster but there are 20 replacements named which could mean multiple changes before the final whistle blows.
Jonny May is back after a bout of illness ruled him out last weekend, James Simpson-Daniel starts his first preseason match and Freddie Burns is back after the knee injury he picked up in the JP Morgan Sevens.
All of the pack who start have seen preseason action with the exception of Huia Edmonds who gets a first start at hooker.
