Chelsea manager Antonio Conte says the club are considering an appeal against captain John Terry's red card in Sunday's FA Cup win against Peterborough.
Terry slid and brought down Posh striker Lee Angol with his side already 3-0 up and referee Kevin Friend decided he was the last man.
"You have to respect the decision, but in this case maybe we will do an appeal for this situation," said Conte.
Speaking after the Blues' 4-1 third-round win which was Terry's first start since October.
The defender, in his 19th season at Stamford Bridge, has played just six minutes since that 2-1 defeat by West Ham in the EFL Cup.
Terry's foul brought a straight red card, but as it was not violent conduct and he has not been dismissed before this season, he faces a one-game ban.
Should any Chelsea appeal not be successful, he will be suspended for their Premier League trip to champions Leicester on 14 January.
