Saracens winger Chris Ashton has lost his appeal against a 10-week ban, meaning that he will miss England's Six Nations campaign.
The 28-year-old was cited in January for allegedly eye-gouging Luke Marshall.
The incident occurred during a European Champions Cup match between Saracens and Ulster at Allianz Park.
Ashton, who joined Saracens from Northampton in 2012, appealed the sanction, but after a hearing on Wednesday, an independent committee opted to uphold the suspension.
The winger will not be eligible to play again until March 28.
