Britt McHenry chose the wrong day to mess with the Sager family.

Kacy Sager, daughter of the late Craig Sager, ripped into McHenry after the ESPN has-been claimed on Wednesday that Sager’s brother broke into sports reporting due to nepotism. McHenry’s cheap shot at the Sager scion came just two days before the anniversary of Craig Sager’s 2016 death at 65 to leukemia.

In her blistering takedown, posted Friday, the younger Sager wrote:

“Britt. Britt, Britt, Britt, Britt, Britt. Might be time for an intervention dear … FIRST OF ALL, it really bums me out to see someone whose career held so much promise just a few years ago, someone I used to have a lot of respect for, have enough free time on her hands to engage in a petty Twitter argument with my brother’s ex. “Maybe pick up knitting or something. Hell, you can take over my fantasy basketball team if you’re that bored.”

Sager, a sportswriter herself and statistician for Turner Sports, wrote how she woke up on the emotional Friday morning to dozens of messages showing sympathy for her family, though one outlier included a screenshot of McHenry’s tweet insulting her brother, Craig Sager Jr.

The message, which has since been deleted, was in response to a Twitter feud that had broken out between McHenry and Sager Jr’s ex-girlfriend, Brenna Simon.

McHenry, a former ESPN reporter who’s been in the middle of a number of controversies during her career, referred to Sager Jr, who’s followed in his dad’s footsteps with the NBA on TNT, as “some kid whose only connection to media is his famous dad.”

Sager’s dig comes eight months after McHenry was included in ESPN’s sweeping April layoffs, which McHenry hinted at the time was a result of her conservative views (in another deleted tweet). Since leaving the network, the 31-year-old Northwestern journalism grad has been active on social media and on the air with Fox News broadcasting her political beliefs.

What sparked Sager’s fiery words was McHenry’s argument with Simon over McHenry suggesting some men, including one she knows of, have been unfairly accused of sexual harassment when those said relationships were consensual.

“While you’ve been busy single-handedly tanking the value of a degree from Northwestern, Craig has kept his head down and built the foundation for a career that will certainly outlast the one you pissed away by being a spoiled brat,” Sager continued. “Why take a shot at him at all? Why lash out at him when he wasn’t even part of the conversation?

“It’s not like he towed your damn car…,” Sager added, referring to the time McHenry was suspended from ESPN after a video of her lashing out at a towing company employee went viral.

Sager suggested McHenry do some “soul searching” before insulting someone else she doesn’t know.

“And in the meantime, don’t f*** with my family,” Sager concluded the post. “#SagerStrong”

McHenry apparently did not take Sager’s advice to heart and shot back on Twitter in what seemed to be a response to Sager’s post.
