Plymouth Albion centre Keni Fisilau has been suspended for two weeks by an RFU disciplinary panel for picking up three yellow cards.
The 35-year-old Tongan was sin-binned in Championship games against Rotherham Titans, London Scottish and Leeds Carnegie in September and October.
Fisiulau, who did not play against Ayr in the British and Irish Cup, will also miss this week's trip to Nottingham.
He will be available for the home game with London Welsh on 26 November.
Fisilau was given a two-week suspension in December 2008 by the RFU after amassing three yellow cards in National One.
