Chelsea captain John Terry will serve a one-match suspension after the Football Association rejected an appeal against the red card he received during Sunday's 4-1 FA Cup third-round win over Peterborough United.
Speaking after the match, Conte suggested a covering defensive run made by Branislav Ivanovic meant Terry was not denying a clear goalscoring opportunity, although the FA has rejected this claim and any other possible mitigation.
"John Terry will serve a one-match suspension with immediate effect after his wrongful dismissal claim was unsuccessful, following an Independent Regulatory Commission hearing," read a statement on the organisation's official website.
"The Chelsea defender was sent off for denying an obvious goal-scoring opportunity during the FA Cup third-round tie against Peterborough United on Sunday."
Terry will miss Saturday's trip to face Premier League champions Leicester City, although he has not started in the top flight for Conte's league leaders since the 2-2 draw at Swansea City in September.
