Moseley have cited Northampton scrum half Mark Robinson for allegedly punching second row Richard Stott in last week's bad tempered National One match at Franklin's Gardens.
The former New Zealand half back will appear before a Rugby Football Union disciplinary committee on Monday, October 1 where he will answer a charge of striking contrary to Law 10.
The Billesley Common outfit have also banned prop Neil Bayliss for one week after the tighthead was sent off for fighting with Simon Emms. Both players will join Robinson in front of the panel next month.
Moseley's anger at the situation has not been helped by the fact Stott was knocked out and will miss this weekend's encounter with Exeter Chiefs.
That leaves them short at lock and could mean Canadian international Oliver Atkinson makes his debut tomorrow - assuming he recovers from the knock he picked up in Monday night's A team win over Stourbridge.
"We had a meeting on Tuesday and we felt there was an unwarranted attack one of our players," head coach Ian Smith said. "Normally we would like to keep this sort of thing in the club but we felt in this case we had not option but to cite.
"It would be far better if it was taken out of our hands and an independent citing commissioner is brought in as soon as possible."
