Saracens number eight Billy Vunipola will not face a ban for striking Matthew Tait, as his case was dismissed.
The England international was accused of deliberately hitting Tait with his head during his side's 22-6 win over Leicester Tigers last weekend.
However, a three-man panel in London has found him not guilty and he will be able to play against Clermont Auvergne in the European Champions Cup semi-final on Saturday.
Vunipola scored a try in the game at Allianz Park, which extended his side's unbeaten run to seven games.
