The Arizona Cardinals have hired the NFL's first female coach in Jen Welter.

Welter is a former collegiate rugby player who played 14 seasons of pro football, mostly in the Woman's Football Alliance.

Welter will serve as a training camp/preseason intern coaching inside linebackers.

“Coaching is nothing more than teaching,” Bruce Arians said Monday. “One thing I have learned from players is, ‘How are you going to make me better? If you can make me better, I don’t care if you’re the Green Hornet, man, I’ll listen.’ I really believe she’ll have a great opportunity with this internship through training camp to open some doors for her.”

Welter holds a master's degree in sport psychology and a PhD in psychology.

“She came for an OTA and I met her, and I thought she was the type of person that could handle this in a very positive way for women and open that door,” Arians said.
