Goran Popov has made an official apology after being sent off for spitting during West Brom's 1-0 home defeat to Tottenham on Sunday.
Walker is currently on international duty with England and Popov says he will call him to apologise. Popov said: "When I get his number I will call him and just say 'I'm not a player like this, I didn't want to do this to him and a big sorry'."
