Terry told reporters at England's World Cup base at the Royal Bafokeng Sports Campus that he admired Anelka as a player and as a man and felt it was wrong to send him home on Saturday.
He said: "I see they sent him home for voicing his opinion and maybe a few of us (England players) will be sent home after this evening!"
Anelka was sent home after allegedly insulting France coach Raymond Domenech last Thursday during their 2-0 defeat by Mexico in a Group A game at Polokwane.
Terry was referring to a planned crisis meeting of the England squad with manager Fabio Capello scheduled to take place later on Sunday evening.
He added: "But I can speak honestly about Nico. He is a really good guy.
"Before he came to Chelsea, a lot negative stuff was written about him but as a person you won't find a better man in football.
"He is very quiet but he has been in the game a long time and he knows his football so, if Nico had something to say to me, I would stand up and listen - because he is a great player as well
"It is obviously the wrong decision."
