Jen Welter hired by Cardinals; believed to be first female coach in NFL 18m - NFL Arizona Cardinals Play Josh Weinfuss, ESPN Staff Writer TEMPE, Ariz. -- In March, Arizona Cardinals coach Bruce Arians was asked when the NFL would have a female coach. Weinfuss: Five things to know about Welter Five things to know about new Arizona Cardinals assistant coaching intern Jen Welter, who is believed to be the first female coach in NFL history. The answer was Monday. The Cardinals hired Jen Welter as an assistant coaching intern for training camp and the preseason to work with inside linebackers. She is believed to be the first female coach of any kind in the NFL. "Someone asked me yesterday, 'When are we going to have female coaches?'" Arians said. "The minute they can prove they can make a player better, they'll be hired." Welter took to Twitter after the announcement. Welter, 37, has been making history throughout her career. In February, she became the first female coach in a men's professional football league when she was hired by the Texas Revolution of the Indoor Football League to coach linebackers and special teams. The Revolution's general manager is Hall of Fame wide receiver Tim Brown. In February 2014, she became the first female to play a non-kicking position in a men's professional football league when she played running back and special teams for the Revolution. Welter played professional football for more than 14 years as a linebacker, mostly with the Dallas Diamonds of the Women's Football Alliance. She helped lead them to four championships. Jen Welter will work with inside linebackers during training camp and the preseason. Courtesy Texas Revolution She will join linebackers coaches Bob Sanders, Larry Foote and recently hired Levon Kirkland. A news conference is scheduled for Tuesday. Speaking to azcardinals.com on Monday, Arians said: "Coaching is nothing more than teaching. 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, I'll listen.'" "I really believe she'll have a great opportunity with this internship through training camp to open some doors for her,'' Arians said. It's the second such barrier to be broken in the NFL this year. The league announced in April that Sarah Thomas would be the first woman to be a full-time NFL official.
