Newcastle United manager Joe Kinnear insists he will appeal against his latest Football Association charge.
The 61-year-old is said to have used abusive and insulting words towards an assistant referee in the closing stages of Saturday's 2-2 draw with Stoke City, but insists he has done nothing wrong.
Kinnear, who was sent to the stands by referee Mike Riley, said: "I'm going to defend myself against any charge because, on this occasion, I've done nothing wrong and I'm determined to clear my name.
"I still haven't been told exactly why I was sent from the dug-out, but I believe it was for supposedly saying something to the linesman. I'll fight this because I'm frustrated and disappointed it's happened.
"The thing that I find strange is I've no idea how the linesman has heard what I've supposedly said from where he was standing and with all the noise that was going on.
"Chris (Hughton) was having his say and I did say something, I know what I said, but I'll wait until I have to give my defence before I talk about that any more.
"There was plenty of noise around, the fans behind the linesman were absolutely furious and they were saying plenty to him as well, the whole place went crazy."
Kinnear is already facing a separate charge of improper conduct for calling Martin Atkinson "a Mickey Mouse referee" after last month's 2-1 defeat at Fulham.
