Terry was an unused substitute as the Premier League champions beat their League One opponents 2-0 to reach the fourth round.
Chelsea boss Guus Hiddink said: "They had a good celebration in our locker room, together with our players.
"These are difficult games. It was their final. They made us shiver a bit. They wanted to exchange the shirts. It was a big day for them and for us, because we wanted to go into the next round."
