England lock Danny Grewcock has been banned from rugby until 31 August after a disciplinary hearing in Auckland.
The Bath captain was cited for reckless use of the boot during England's 36-12 second Test defeat against New Zealand.
Grewcock will now miss next Saturday's World Cup final rematch against Australia in Brisbane.
Team-mate Simon Shaw, however, is free to play after being cleared of foul play despite being sent off against the All Blacks for use of the knee.
The decision to send off Shaw, who kneed New Zealand lock Keith Robinson in the back, incensed England coach Sir Clive Woodward.
The disciplinary panel ruled Shaw could not be banned since Australian touch judge Stuart Dickinson, who recommended the sending-off, had breached protocol by asking for help from the television match official to identify the 'culprit'.
"The rucking was clumsy, but there was never any malicious intent on my part," Shaw insisted after the tribunal.
"When the referee brought out a red card, I was astonished. I thought the crowd was a factor in the whole incident, because it was shown on the television screen and lots of people were chanting 'off, off, off'.
"The judicial process was fair and just, and I am absolutely delighted with the result.
"I wasn't too concerned, because I believed that I had a strong case, and there was never any malintent on my part."
Robinson himself said: "I didn't know what had happened... I can't say he hurt me in any way."
Shaw's relief and support from Woodward contrasted with Grewcock, who pleaded not guilty to a charge of reckless use of the boot to All Blacks centre Daniel Carter's head.
But the judicial committee - chaired by Australian Michael Goodwin and assisted by two New Zealanders, Pat Samson and Ash Edwards - determined the contact was "careless and reckless".
They banned Grewcock for six weeks, but since the ban means he will only miss Saturday's Test against Australia, decided to keep it in place until 31 August.
The Zurich Premiership season does not start until 4 September.
"I fully accept the decision," Grewcock said.
"It is disappointing not to have the opportunity of playing against the Australians, but still, I am looking forward to getting back to playing for Bath in September."
Grewcock's ban is the latest in a series of indiscretions that has chequered his career.
The 31-year-old, who would have won his 50th cap against Australia had he been
selected, was sent off playing for England against New Zealand in 1998.
He was also red-carded twice in club colours during the 2002/03 season,
although his first sending off - against Saracens - was quashed on appeal.
The second dismissal - for punching England team-mate Lawrence Dallaglio in the Parker Pen Cup final - meant he missed England's Test in Wellington last year.
