Chris Ashton will miss England's international against Fiji on 10 November after being handed a one-game ban for picking up three yellow cards.
The Saracens wing received a retrospective yellow card for a dangerous tackle on Vasily Artemyev during last Saturday's win at former club Northampton.
That took him to three yellows for the season and triggered an automatic disciplinary hearing.
A Rugby Football Union disciplinary panel of Jeff Blackett, Jeremy Summers and Peter Budge decided to slap him with a one-match ban.
The suspension begins on 4 November, which rules Ashton of England's first game of the autumn internationals against Fiji at Twickeham.
However, the 25-year-old will be available for the games with Rugby Championship heavyweights Australia, South Africa and New Zealand.
Ashton's suspension opens the way for Ugo Monye and Charlie Sharples to be England's likely starting wings against Fiji.
In the meantime, Ashton has been urged by the RFU's disciplinary panel to work on his tackle technique after effectively receiving three yellow cards for dangerous play this season.
Panel chairman Judge Blackett said: "We are concerned about his tackling technique and encouraged that he and his coaches work to correct it.
"We were guided by the IRB recommendation that a one week suspension was appropriate for totting up offences.
"The player was not released back to his club by England for Saracens' game on Sunday, November 4 so it would be inappropriate to commence the suspension immediately.
"We have therefore deferred commencement until Sunday November 4 so he misses a game he would have played in.
"We would like to add that Chris Ashton took a realistic and mature approach to proceedings and expressed genuine contrition."
