Kyle Sinckler will miss England's opening game in this year's Six Nations after the prop was handed a two-week ban for swearing at a referee.
The Bristol Bears forward was cited by an independent commissioner for failing to respect the authority of a match official during Saturday's Premiership game against Exeter Chiefs.
Sinckler contested the charge at a disciplinary hearing, during which he accepted he had used foul language.
The 27-year-old was handed a suspension by an independent panel and will now be unavailable until February 9, three days after England open their 2021 campaign against Scotland.
"The player was candid in his evidence as to why he had done so and regretted his actions," a statement from the independent panel read.
"The panel found that his actions disrespected the authority of the referee and it was in breach of a core value of rugby - respect of match officials - and warranted a red card.
"The panel determined that in all the circumstances it was a low entry point with no relevant mitigation. The sanction is a two-week ban."
Following on from the Calcutta Cup clash at Twickenham, Eddie Jones' squad host Italy on February 13.
The Six Nations is scheduled to go ahead amid the ongoing coronavirus pandemic, though the European Champions Cup and Challenge Cup have been temporarily suspended after French authorities ruled the participation of Top 14 clubs to be too much of a public health risk.
