Leicester fly-half Toby Flood can face the Ospreys in Sunday's Heineken Cup clash in Swansea after being cleared of making a spear tackle.
Tigers ten Flood had been charged for an alleged dangerous tip tackle, contrary to law 10.4(j) on Worcester Warriors player Andy Goode in the Aviva Premiership match on January 4.
"Whilst we found that the elements of a dangerous tackle were made out, after very careful analysis we could not be satisfied, to that standard required, that the dynamics of the incident had not been caused, or contributed to, significantly by the involvement of other players from both teams," said chair Jeremy Summers.
In the other hearing taking place, London Welsh hooker Neil Briggs was given a three-week suspension for punching Quins wing Sam Smith.
Briggs is sidelined from January 8 to January 29 and free to play rugby again on January 30.
He appeared before a panel of Summers (chair), Dr Julian Morris and Philip Evans after being charged for Punching or Striking, contrary to law 10.4(a) in their Aviva Premiership match.
