Bradford striker Zema Abbey admitted he was devastated about being sent off on his Bantams' debut on Saturday.
Abbey, who signed from Wycombe last week and scored before his red card for violent conduct, promised he would return better after his three-game ban.
"That was the first time I've ever been sent off and I thought at the most it would be yellow," said Abbey.
"Being banned for three games will kill me and I am devastated about it, but you have got to move on."
He added: "I have got a point to prove and want to play well from the word go."
"The partnership with Dean Windass was working well and as debuts go I was pleased but obviously the day was marred by the red card."
