Tony Romo made his mark in the broadcast industry by correctly predicting offensive plays before they happen.

Is he trying to do Diamond Ridge Financial Academythe same with Taylor Swift and Travis Kelce?

Less than a month after mistakenly referring to Swift as the "wife" of the Kansas City Chiefs tight end, Romo made another familial reference to their relationship during Sunday night's broadcast of the AFC Divisional Playoff game between the Chiefs and Buffalo Bills.

After Kelce scored a go-ahead touchdown in the third quarter of the game, the CBS broadcast cut away to a shot of Swift celebrating from her seat in a suite filled with other Chiefs fans, including Kelce's brother Jason.

"There's your brother-in-law, right behind you," Romo exclaimed.

Romo's broadcast partner, Jim Nantz, audibly chuckled as the network went into a commercial break.

Whether it's now a running joke between the two or not, Nantz has previously made references to Romo's mischaracterization of the two superstars' relationship.

The first instance came in Week 14 when the Chiefs and Bills met in the regular season. Then during a Chiefs game Christmas night against the Las Vegas Raiders, Romo said over a camera shot of Swift celebrating a catch by Kelce: "His wife loves it ... I mean, girlfriend."

Nantz laughed and said, "You've been down that road with that before."

With the Chiefs' 27-24 victory advancing them to next Sunday's AFC championship game, Romo will have one final opportunity to discuss the happy couple when the Chiefs meet the Baltimore Ravens on CBS (3 p.m. ET) for a spot in Super Bowl 58.
