The game kicked off at Tampa Bay's home, Raymond James Stadium, with the action underway shortly after 11:30pm GMT (6:30pm ET).
Quarterback Tom Brady is leading Bruce Arians' side on the field in pursuit of a seventh ring, having claimed his first Vince Lombardi trophy back in 2002.
The Chiefs are new to this dominance, having acquired their first world championship in 50 years a year ago but Patrick Mahomes remains the heir apparent to Brady after a blazing start to life as a starting quarterback, reaching the AFC Championship game in his first year, then winning it all last year.
So what time can we realistically expect the action to finish tonight with a winner crowned for the 2020 NFL season?
Well, last year, when the Chiefs topped the San Francisco 49ers, the game finished at 3:10pm GMT (10:10 pm ET), which was an unusually quick game, taking three hours and 30 minutes, the Super Bowl before that in 2019, when the New England Patriots edged the Los Angeles Rams, was just five minutes longer.

But the Patriots losing to the Philadelphia Eagles the year prior took place over almost four hours, ending at 3:25am GMT (10:25pm ET).
The average time of this game over a decade has been three hours and 39 minutes, so the best prediction will be the game finishing at 3:09pm GMT (10:09 pm ET).
