Former Exeter Chiefs props Jason Hobson and Jack Andrew have both been suspended following a brawl between Plymouth Albion and Bristol players last month.
Plymouth's Andrew was sent off in the match at Brickfields on November 24, which Bristol won 21-8.
He pleaded guilty to a charge of punching when he appeared before a disciplinary hearing on Tuesday evening and was banned for three weeks and ordered to pay £250 costs. He can play again from December 16.
Hobson was cited for 'acts contrary to good sportsmanship' and, after pleading not guilty, was banned for 12 weeks and also has to pay £250 costs. He cannot play again until February 27.
In addition, both clubs pleaded guilty to 'conduct prejudicial to the interests of the Union or the game' and received a deduction of five league points, suspended for 12 months.
