Leicester Tigers have appealed against Richard Cockerill's nine-match ban for his row with the fourth official during the Aviva Premiership final.
Leicester's director of rugby protested angrily to Stuart Terheege after a challenge by Northampton lock Courtney Lawes on Toby Flood in the Tigers' 37-17 win in May.
The Rugby Football Union took severe action against Cockerill after finding him guilty of 'unprofessional and inappropriate' behaviour and use of 'obscene' language.
Leicester reacted by expressing disappointment about the RFU's treatment of Cockerill and the club have confirmed they will appeal the suspension.
A statement read: "Leicester Tigers today gave notice of appeal against the nine-match suspension imposed on director of rugby Richard Cockerill following his exchange with fourth official Stuart Terheege during the 2013 Aviva Premiership final.
"Cockerill was found guilty of conduct prejudicial to the interests of the Union and/or the Game contrary to RFU Rule 5.12 at last month's RFU Disciplinary Hearing.
"Details of the staging of the appeal, which is against the sanction only, will be released in due course."
