London Welsh are to appear at an RFU hearing charged with fielding an ineligible player in a number of Aviva Premiership matches.
The case relating to the registration of scrum-half Tyson Keats will be heard on Tuesday, March 5, by a panel of Jeremy Summers (chairman), Premiership Rugby Chief Executive Mark McCafferty and Dr Julian Morris at the offices of Slater & Gordon, Chancery Lane, London.
The club's former Rugby Manager Mike Scott is the subject of a separate RFU Disciplinary Hearing relating to the registration of the same player and has been charged under RFU Rule 5.12 for 'conduct prejudicial to the interests of the Union or the Game'. That case will be heard at a later date.
Keats joined Welsh from Aironi after previously playing for the Crusaders and Hurricanes in Super Rugby.
The newly-promoted side, who are currently 11th in the Aviva Premiership table and only three points clear of bottom club Sale Sharks, could face a possible points deduction if found guilty.
"This is obviously a serious matter which the club has not only brought to the attention of the RFU but is also working closely with the RFU to provide full cooperation whilst the case is being prepared and ultimately heard next week," said Welsh CEO Tony Copsey.
"Due to the sensitive nature and the impending hearing the club is unable to make any further comment at this time."
