Australia captain James Horwill has been cleared of stamping on Alun Wyn Jones in the first Test in Brisbane on Saturday.
Horwill appeared to make contact with the face of Jones at the ruck during the first half of Saturday's Test match.
The Reds second row had been cited under Law 10.4 b of the IRB's disciplinary rules, for "stamping" or "trampling" on an opponent.
"After hearing all the evidence I could not find that when James Horwill's right foot came into glancing contact with Alun Wyn Jones' face, that he Horwill was acting recklessly," said Judicial Officer, Nigel Hampton QC.
"I found that I could not reject as being implausible or improbable Horwill's explanation that as he was driving forward with his right leg raised he was spun off balance through the impact of Lions players entering the ruck from the opposite side.
"In an endeavour to regain his balance Horwill brought his right leg to the ground unknowing that Alun Wyn Jones' head was in that area, due to having his sight impeded by the presence of Michael Hooper and Tom Croft who were beneath him and over the top of Alun Wyn Jones. Due to these reasons I cannot uphold the citing."
