The backs all keep their places but up front Joe Russell starts at loose-head prop, Alex Luff gets his first start of the season in the second row and Dan Richards reverts to his usual position of back row. With Will Rees unavailable Gareth Knight returns at No 8.
“We expect a typical Gwent reception up in Tredegar, friendly off the field but uncompromising on the field,” said Wanderers forwards coach Matthew Bolton.
“We both find ourselves struggling at the bottom of the table, I would imagine the result is far more important than the performance to both our sides” added manager Gavin Walker.
