It is a third start in a row for Day, while Hobbs and Herriott were also both involved in the opening fixtures against Scotland and Ireland.
Stephenson meanwhile is in line to earn his first cap for the side having missed out on Rounds 1 and 2 due to illness, where England saw off the Scots in Plymouth but then fell a solitary point short in Athlone.
Supporters at the Gardens to watch Saints versus Bath, tickets for which can still be bought by clicking here, can expect regular updates from Worcester throughout the afternoon.
