Breaking: Following her discovery,the wife of , Kyle Shanahan filed for divorce after going out on.

San Francisco 49ers head coach Kyle Shanahan has found success on and off the football field since marrying Mandy Shanahan in 2005.

The couple first met and started dating in high school during the late ‘90s in Colorado while Kyle’s father Mike Shanahan was the head coach for the Denver Broncos. They briefly split up before reconnecting in college, where tragedy brought them closer together.

While in college, Mandy’s mother, Nancy O’Donnell, was diagnosed with Stage 4 gallbladder cancer, which she later died from in 2002. Once Kyle found out about Nancy’s diagnosis, he flew from his college in Texas to Colorado regularly to see Mandy, and he fell in love with her while watching how she dealt with her mother’s illness.

“There are very few times in life you get to see someone for who they genuinely are,” Kyle told the San Francisco Chronicle in 2017. “Mandy going through that — it was as bad as anything you could go through — it showed me who she was. There was no B.S. to her. I saw who she was. And that was the person I fell in love with.”

Kyle and Mandy have welcomed three children together in their nearly two decades of marriage: Their daughter Stella was born in 2007, followed by son Carter in 2008 and daughter Lexi in 2012.

Kyle Shanahan’s dad is none other than legendary NFL head coach Mike Shanahan.

The elder Shanahan won three Super Bowls on the sidelines, including back-to-back Super Bowl titles with the Denver Broncos in the 1997 and 1998 seasons.

The two had the pleasure of working closely together from 2010-2013, during Mike Shanahan’s last years in the NFL. Father Shanahan was the head coach and the executive vice president for the then-Washington Redskins while Kyle Shanahan was the team’s offensive coordinator.

Given how much of the NFL coaching brass stemmed from those Washington teams (Shanahan, Matt LeFleur, Sean McVay, Mike McDaniel), it’s little wonder that Kyle Shanahan was able to follow in his father’s footsteps.

Kyle Shanahan has quickly created a coaching tree of his own.

New York Jets head coach Robert Saleh was a phenomenal defensive coordinator under Shanahan, while Houston Texans head coach DeMeco Ryans took Saleh’s place in 2021 and was the NFL Coach of the Year runner-up this season.

Miami Dolphins head coach Mike McDaniel, who also worked under Mike Shanahan, further developed under Kyle Shanahan in San Francisco as their run game coordinator and their offensive coordinator.

Los Angeles Rams offensive coordinator Mike LaFleur and Houston Texans offensive coordinator Bobby Slowik also worked under Shanahan in San Francisco and will almost certainly end up as NFL head coaches in the near future.
