The NFL has fined Chris Cook $26,250 for bumping an official during Sunday’s game against Chicago, and the Vikings cornerback plans to appeal.

He is skeptical the penalty will be reduced, however.

Cook met with coach Leslie Frazier on Wednesday and was scolded about the bump, which brought an ejection. Cook had just yielded a touchdown pass for the second time to Bears wide receiver Alshon Jeffery.

Cook said the meeting “went pretty well.”

“I know I have to keep my composure,” he said. “I was just frustrated with some things that happened in the game and lost my composure. I can guarantee it won’t happen again.”

Cook was upset with side judge Laird Hayes for not calling offensive pass interference earlier on Chicago’s drive. After Jeffery outmuscled Cook for Josh McCown’s 46-yard pass in the end zone, Cook jumped up and confronted Hayes.

“I kind of touched his arm,” Cook said. “I just got up and said, ‘That was bull,’ about the play two plays before. But I can’t do anything about the calls they make during the game. I’ve just got to be a man about it and move on to the next play.

“I let my emotions get the best of me. I know I can’t react like that, especially towards an official.”

Frazier said Cook has to manage adversity better.

“He just has to be able to keep his composure going forward and handle things the right way,” he said. “There are going to be negative things that happen on the field, and he has to handle it the right way.”

Cook, a 2010 second-round pick out of Virginia, has had a rocky tenure with the team. He has been beaten in one-on-one coverage several times this season and does not have an interception in his career. He also has been at the center of controversy.

As a rookie, Cook had to be restrained on the sidelines following a confrontation with veteran linebacker Ben Leiber during a blowout loss to Green Bay at the Metrodome.

In 2011, he was charged with felony domestic assault following a confrontation with his then-girlfriend. A Hennepin County jury acquitted Cook, whom the Vikings suspended six games while his trial was pending.

With four games remaining, Cook is a pending free agent with an uncertain future in Minnesota.

“My future — that’s really the biggest thing that’s at stake for me,” he said. “It’s a contract year. It’s been a pretty rough year by my standards. I’ve just got to go ball out these last four games.”
