WATCH: Travis Kelce honors Tony Gonzalez celebration after breaking former Chiefs tight end's TD record

Travis Kelce keeps adding milestones to his illustrious NFL career, confirming that he's Patrick Mahomes' most reliable partner and a key part of the Kansas City Chiefs' success. The veteran tight end made history against the Pittsburgh Steelers on Christmas Day, adding another touchdown to his account, surpassing Chiefs legend Tony Gonzalez, with 77 scores.

Kelce couldn't find a better way to celebrate the big moment than to copy Gonzalez's celebration: dunk the ball in the middle of the post. That prompted the referees to throw a flag and penalize him.

This was the second time the Chiefs were flagged for an unsportsmanlike penalty. The first time was when Xavier Worthy celebrated by simulating throwing gifts to an invisible bag carried by Marquise "Hollywood" Brown after scoring the first touchdown.

This shouldn't be a problem for Kelce, as Gonzalez had vowed to pay the fine if the three-time Super Bowl champion dunked the ball.

He scored the final touchdown for the Chiefs, giving them a 29–10 win after Harrison Butker completed the extra-point attempt. They secured the No. 1 seed in the AFC after beating a team that looked like a threat in the playoff and won their third game in 11 days.

Furthermore, Mahomes played exceptionally, showing he's ready for the playoffs.

Tony Gonzalez reacts to Travis Kelce breaking his Chiefs touchdown record

In a video shared by NFL on Prime Video on X, Tony Gonzalez congratulated Travis Kelce on breaking his record. He celebrated his growth and shared his feelings about his fellow tight end.

“What’s up Travis?” Gonzalez said. “Congratulations on breaking the all-time Chiefs touchdown record. A lot of big names that you passed - including me - but I just want to say congratulations man.

Watching you grow as a player on the field, off the field, everything you’ve done for the game, for the position … couldn’t be prouder of you, couldn’t be happier for you. Keep it up - you got a lot more to go, OK, ‘cause I know you got it in you. Good luck to you brother. Congrats!”

Kelce has broken and set several records during his time with the Chiefs and doesn't seem to be stopping anytime soon. The Chiefs are still going strong, and Kelce plays a big role in their good season.
