Jim Caldwell said he's done pursuing head coaching jobs in the NFL. Caldwell is currently senior assistant of the Carolina Panthers. Caldwell has interviewed for more than six head coaching jobs since he was fired by the Detroit Lions after the 2017 season.

"Right now, the only job that I'm concerned about is the job I do here, right here and now," said Caldwell. "I'm not worried about the future or anything else. I don't plan on being a head coach from this point forward."

Caldwell said he will continue to strive to get more Black head coaches in the league. He just won't be part of that group.

"When you look at the numbers, they speak for themselves,'' he said of the league's track record for hiring Black head coaches. "There's been volumes and volumes of articles written and reporting on television about the lack of diversity in terms of the head-coaching position.

"But there's been a lot of things in the background to try to improve that."
