Both Leeds Rhinos and Catalans Dragons will have a nervous wait today before they will know who is available for this Saturday's massive clash between the two. For the Champions, Matt Diskin and Ryan Bailey will both have scans today to ascertain the extent of the injuries they suffered in the win over Huddersfield last Friday. Diskin is rated as very doubtful for the trip to France although Bailey's injuries is thought not to be as bad as the hookers. Meanwhile, Catalans have had two players out of seven ordered to appear before the Rugby Football League's disciplinary committee on Tuesday after a stormy match between them and Harlequins. Dragons stand-off Adam Mogg and Harlequins prop Louie McCarthy-Scarsbrook, who were both sent off following a last-minute skirmish, have been charged with allegedly running in and punching. Catalans hooker Casey McGuire and the Harlequins trio of David Howell, Rikki Sheriffe and Michael Worrincy must also face the disciplinary panel after being charged with punching. All are on grade C charges which carry a suspension of up to four matches. The Dragons were awarded a penalty as a result of the brawl and from it scored the match-winning try through full-back Clint Greenshields. Their 32-26 triumph extended their club record winning run to seven and took them to within a point of Leeds, who are the visitors to the Gilbert Brutus Stadium on Saturday.
