Kyle Sinckler will miss England's autumn internationals against Argentina and Australia after being given a seven-week suspension for gouging.
The Lions tighthead appeared at a Rugby Football Union disciplinary hearing on Tuesday night after being cited for making contact with the eye and/or eye area of Michael Paterson in Harlequins' defeat at Northampton last weekend.
"The panel heard evidence from the player as to his actions. They found that it was an intentional action, but that due to the absence of injury it merited a low end entry point," panel chairman Dan White said.
Sinckler protested his innocence when accused of gouging by Paterson, who drew the incident to the attention of referee Luke Pearce, but at the hearing he accepted the charge of making contact with the eye.
The 24-year-old - England's second choice tighthead - is free to play from 21 November, but, having spent seven weeks on the sidelines, he is highly unlikely to feature in the final autumn international against Samoa four days later.
"The player has not got a clear record because of a suspension in 2015 and so the panel could not give full mitigation," White said.
"The player will therefore be suspended for seven weeks and is free to play again on the 21 November 2017."
The entry point sanction for the offence is 12 weeks, meaning five weeks were shaved off by the panel.
