He said: ‘Hey, look at that now. She’s got the part on. That looks good,’ referencing the singer’s outfit.

Fans were quick to share their thoughts on the moment, with Jason receiving glowing praise.

One commented: ‘Ngl (not gonna lie) he earned some big points the way he just got on MNFL live and defended his brother and Tay like that. That’s family.’

Another posted: ‘Jason is all of us tonight.’

‘Brilliant,’ added a third fan.

Swift was in the mood to celebrate as she appeared on the Instagram story of Chariah Gordon after the game – the partner of Kelce’s teammate Mecole Hardman.

Swift appeared to be in Kelce’s suite – there was picture of her performing on her Era’s Tour in the background – and she was asked by Gordon what she thought of the victory.

‘No, it’s important that you answer the question this time,’ Swift said, before Gordon continued: ‘I think that we feel really good about this week, we are 5-0.’

Swift interjected: ‘Going into a bye week’ before agreeing with Gordon saying the win was perfect: ‘Perfect is the word!’

Monday marked the first time Jason was on the Monday Night Football panel for a Chiefs game and a contest in which Travis was playing.

Last season, as a Philadelphia Eagle, Jason played on the road against the Chiefs and was victorious in his final on-field clash against his brother.

Speaking about Travis’ form so far this season, which had attracted plenty of criticism before Monday night’s game, Jason said: ‘Now he’s enjoying his life very publicly.

‘Everything he does and everything, really our family does is very much out there and that’s just the nature of the way it is right now.

‘I think that Trav, he’s been very healthy throughout his career. This is a guy who’s always found a way to show up in the peak physical shape.

‘And I know optics are that he is all over the place, and that’s not dishonest of reality, but he still keeps the main thing. Football has always been the most important thing in Trav’s life.

Travis had one of his best nights of the season, amassing nine catches for 70 yards

Swift declared the victory ‘perfect’ as Kelce and the Chiefs now head into their bye week

‘He has always lived his life to the fullest. He has enjoyed his offseasons very much, even before Taylor Swift and everything else going on in our lives. And I think that, you know, he is always going to find a way to make football the No 1 priority in terms of being prepared.

‘There’s so many things that rely on this, between his relationship with his teammates, Andy Reed, and his legacy.

‘So I know it’s been a slow start for him. Trav is always gonna find a way to show up and show out. I think it’s only a matter of time before it gets back to the Travis Kelce we’ve seen.’

During the evening, Jason was seen kissing wife Kylie during a commercial break while he was on the Monday Night Football panel.

Also during another commercial break, the quartet on ESPN’s pregame show signed a fan’s prosthetic leg.
