Arizona Cardinals fans are singing the praises of Jennifer Welter, who just became the first woman hired as a coach at any level of the National Football League.

Welter joins the "Birdgang" as a training camp and preseason intern coach for inside linebackers.

"I'm proud to be part of the Birdgang," she tweeted right after the announcement. "Love the football family here at the Arizona Cardinals."

She's no rookie, though.

Back in February, she became the first woman coach in any pro-football league when the Texas Revolution of the Indoor Football League named her as a special teams coach.

She was also a groundbreaking player, working as a running back for the team and becoming the first woman in a non-kicking position on a professional football team.

Before that, Welter was a linebacker for 14 seasons in the Women's Football Alliance, where she played mostly for the Dallas Diamonds. She helped lead them to four national championships, which is two more than the Cardinals have won - their last one was in 1947.

Her extensive resume also includes a master's degree in Sport Psychology and PhD in Psychology.
