Bath forward Niall Annett received an autographed red card from ref Tom Foley to commemorate his pre-debut sending off earlier in the season.
Reacting to the gift, one fan wrote: “As an extra kick in the nuts, Foley spelt Annett’s first name wrong.”
A second wrote: “This is brilliant haha,”
Ellis Genge scored two tries on his Bristol return to help his side to a late 31-29 win over the Black, Blue and Whites back in September.
Luke Morahan gave the Bears a half-time lead, with the man who joined from Worcester sent off after a post-try melee.
Annett said after the game on Twitter: Just want to apologise to everyone associated with Bath.
“Not how I saw my first game going and deeply embarrassed and disappointed in myself. Players, staff, fans and everyone else associated, sorry for my actions.
