Travis Haney may want to keep an eye on his Twitter notifications.

Hours after Erin Andrews reported from the sidelines of Super Bowl LI, former ESPN co-worker Haney fired off a scathing tweet alleging the Fox broadcaster, who is recovering from cancer, had treated him “rudely” in the past.

I've never been treated more rudely by someone in sports media than Erin Andrews. I'm sure others share the same experience. Unfortunate.

Though Haney, who currently writes for recruiting website 247Sports, didn’t disclose details of the beef, he followed up with a second post claiming others have felt Andrews’ wrath.

The texts I'm receiving suggest I'm not the only one. https://t.co/NDzhTVCjtN

Haney once sang Andrews’ praises on social media. In a series of tweets captured by Busted Coverage, Haney once called his current adversary “classy” for mingling with fans.

“@ErinAndrews is patiently making her way around the crowd, signing autographs. She’s been signing for 15 min. Classy stuff,” he wrote in October 2010.

Though the newly engaged Andrews has yet to reply to Haney’s tweets, Twitter feuds are nothing new for the sports personality. Andrews hit back at internet trolls last summer after they took jabs at fiancé Jarret Stoll’s 2015 cocaine bust in Las Vegas.
