Worcester Warriors centre Josh Matavesi is in danger of missing his side's final two games of the season after being cited for a high tackle in Sunday's 47-17 defeat at Saracens.
The Fijiaian is due to appear at a Rugby Football Union disciplinary hearing on Tuesday.
Matavesi is charged with an alleged dangerous tackle contrary to Law 10.4 (e) on Neil de Kock.
Warriors crashed to their latest Premiership away defeat at Saracens.
They have now not won the road in the league since January 2012 - and now have just one chance to put that right this season - at already relegated London Welsh on 4 May.
