Gloucester prop Nick Wood has received an eight-week ban for stamping on Saracens forward Jacques Burger during last Sunday's Aviva Premiership game between the clubs.
Wood, who was sent off in the second minute by referee Wayne Barnes, cannot play again until November 13, the Rugby Football Union announced.
The 30-year-old appeared before a three-man RFU disciplinary panel in Bristol on Wednesday night.
Wood, who is a member of the current England Saxons squad, apologised to Burger after the incident.
However, Gloucester - currently bottom of the Premiership with just one point from two games - will be without the loosehead prop's services for five league matches and two Heineken Cup fixtures.
His case was heard by a panel comprising chairman Christopher Quinlan QC, Mike Curling and John Doubleday.
Burger said earlier this week that he harboured "no hard feelings" towards Wood following the incident.
