New Zealand World Cup winner Jerome Kaino will not face Leinster this weekend after being served with a five-week ban for a shoulder charge on Wales international centre Jamie Roberts.
Kaino was cited following the incident - he struck Roberts with his shoulder - during last Saturday's Heineken Champions Cup game between Bath and Toulouse.
Bath centre Roberts was briefly knocked out following the 39th-minute incident - Kaino received a yellow card - and took no further part in the Recreation Ground clash that Toulouse won 22-20.
Back-row forward Kaino, who joined Toulouse earlier this year following an 81-cap All Blacks career, appeared before an independent disciplinary committee in Paris on Wednesday after being cited by match citing commissioner Eugene Ryan. He pleaded not guilty.
He is now suspended until 3 December, starting with Toulouse's Champions Cup game against European title holders Leinster on Saturday.
In a statement, tournament organisers European Professional Club Rugby said: "The committee upheld the citing complaint as it determined that Kaino had committed an act of foul play that warranted a red card.
"On the basis that the incident involved contact to the head, the committee was obliged under World Rugby regulations to find that the offence was at least at the mid-range of the sanctions, and six weeks was selected as the appropriate entry point.
"In the absence of a guilty plea, but in consideration of the player's good conduct at the hearing, the committee decided to reduce the sanction by one week before imposing a five-week suspension."
Kaino's Toulouse team-mate - prop Lucas Pointud - has received a four-week ban following an incident in the Bath game.
He was initially cited for striking Bath prop Nathan Catt with his head. A disciplinary committee in Paris determined it had been Pointud's shoulder that made contact with Catt's head, and that the offence warranted a red card.
Pointud, who pleaded not guilty, is suspended until 26 November.
