The hosts make six changes to the starting line-up for the National One clash, with Hayman replacing last week’s try-scorer Pete Austin at hooker as he becomes the latest player to reach a century.
The second alteration has James Baker going from the off at tight-head, Paddy Harris on the other side of the scrum.
Liam Elston comes into the second row for his first start since returning from his travels, Connor Stapley alongside in the engine room.
The final swap in the pack sees Ben Atkins, who impressed off the bench at Bishop’s Stortford last time out, come into the side at open-side flank.
Summer signings Aaron Tull and Willo Bicknell complete the forwards at blind-side and No. 8 respectively.
Two changes in three-quarters
The half-backs remain unchanged with Ed Hoadley looking to pull the strings alongside Mike Cooke, the ever-present stand-off leading the points tally with 53 to date.
The midfield also remains the same, Morgan MacRae’s double in Hertfordshire taking his try total into double figures with Rowan Grundy outside him.
Oli Rhoads retains his place on the left wing after gaining a late call-up last Saturday, with the final two changes seeing fit-again Luke Graham and Zach Clow return in the back three.
The former, with five tries in four appearances this term, slots in for Axel Kalling-Smith who is on international duty for Sweden in Czechia.
Clow, meanwhile, who has four scores this season and 37 in 58 Rams’ career appearances, rounds the side out at full back.
Brown set for debut
Centurion Ant Marris is back on the bench to cover loose-head prop, with Ryan Lomas the other front row option.
There is a debut for versatile off-season recruit Max Brown, the powerful Cardiff Met graduate having impressed for the Development XV and capable of playing anywhere across the back five of the scrum.
Andrew Lamb drops to the bench with Clow back in, able to cover fly-half as well, while scrum-half Ollie Hodgson completes the matchday 20.
Seven travelling reserves will be on hand at OBR in the form of Max Marshall, George Breese, Austin, Harry Bicknell, Paddy Jackson, Louis Pereira and Ellis Jones.
