Jersey have banned full-back Barry Davies for two weeks following a brawl towards the end of their last Saturday.
The off-the-ball incident also led to teammate Dave Markham and Rotherham's Daniel Sanderson being sin-binned.
Davies' ban runs until 12 February and he misses the away game at Bedford.
He last year after three seasons with Ospreys and won a Welsh cap against Ireland in the 2006 Six Nations.
"Club officials reviewed the relevant footage from the match at St Peter and decided there was a case to answer regarding alleged foul play," said a club statement.
