Leinster prop Cian Healy has successfully won his appeal against a two-week suspension, but will face another hearing for his original incident against Toulon.
The Ireland international was cited over a clash with Toulon hooker Guilhem Guirado during December 13's European Champions Cup match.
An initial charge of striking with the knee was not proven, and was amended by Welsh judicial officer Roger Morris to " Dangerous charging or obstructing or grabbing of an opponent without the ball, including shouldering", in breach of Law 10.4 (f) and (k) of World Rugby's regulations.
Healy's successful appeal means he is free to face Munster in the inter-provincial derby, but the saga is not yet over and will face another hearing for the Champions Cup incident.
"The Appeal Committee determined that the decision of the independent Judicial Officer at a Disciplinary Hearing on Thursday, 17 December 2015 should be set aside, and Healy is therefore free to play with immediate effect," today's statement read.
"However, the Appeal Committee also decided that the original citing complaint against the player should be reheard at a later date by a different independent Judicial Officer from the Disciplinary Hearing.
"The Appeal Committee consisting of Professor Lorne Crerar (Scotland), Chairman, Rod McKenzie (Scotland) and Roddy Dunlop QC (Scotland), heard submissions by video conference on behalf of Healy by Leinster Rugby's legal representative, Donal Spring, and on behalf of the EPCR Disciplinary Officer, Liam McTiernan."
