Joe Marler has been suspended for two matches and fined £20,000 (NZ$41,650) to be paid to a suitable equality charity in the UK after an independent judicial committee upheld a misconduct charge against the player at a hearing in London today.
Marler was heard calling Wales prop Samson Lee a "Gypsy boy" in England's 25-21 win over Wales on March 12.
A misconduct charge was brought by World Rugby against Marler in relation to a breach of Regulation 20 and the code of conduct.
Governing body World Rugby announced a three-man independent judicial committee last week, after both the Rugby Football Union and Six Nations had taken no further action.
Marler apologised to Lee at halftime and was reprimanded by England head coach Eddie Jones, but the decision not to sanction him caused an outcry.
