Australia captain James Horwill says he has been 'vindicated,' after a appeal over an alleged stamp on Wales second row Alun Wyn Jones was dismissed.
He has now been cleared to play in the series decider on Saturday.
Horwill stood on Jones' head in the opening minutes of the first test between the British and Irish Lions and Australia. Jones needed stitches to a wound above his eye.
A disciplinary hearing held 24 hours later concluded that on the balance of probabilities there was no act of foul play. The International Rugby Board announced on Thursday that it was appealing.
Independent appeal officer Graeme Mew upheld the original judgement and said that only a major error during the original hearing would warrant the 'not guilty' verdict being overturned.
Sam Warburton stayed in Melbourne, after Saturday's defeat against the Wallabies, to undergo a scan on his leg.
The Lions have now confirmed that he suffered a 'significant tear in his left hamstring.'
He will remain with the tour party, but will not play in the final test.
Warburton said: "It is incredibly disappointing to be ruled out of the tour through injury as we head to Sydney for the deciding match.
"I wish the team all the best and hope I can play some part in the build up this week. I am confident that the boys can finish the job off and secure the series win."
The British and Irish Lions have confirmed captain Sam Warburton has been ruled out of Saturday's final test after picking up a hamstring injury.
British and Irish Lions captain Sam Warburton is to undergo a scan today after injuring his hamstring during the 16-15 second Test defeat against Australia in Melbourne.
He limped off 13 minutes from the end of the match as Australia gained a dramatic series-levelling victory to set up a decider in Sydney next Saturday.
The Lions announced that Warburton will remain in Melbourne on Sunday for the scan.
On Monday he will join up with the rest of the squad, who will now decamp to the Queensland surfers' resort of Noosa until Thursday.
