Owen Farrell will miss the first two pool games at the World Cup after World Rugby successfully appealed against the decision to overturn his red card.
The England captain's four-game ban means he will miss the group games against Argentina and Japan, with two warm-up matches also included.
Farrell's red card was overturned by an independent judicial committee, which itself was then overruled on Tuesday.
The Appeal Committee said the tackle was "always illegal".
