After 12 years of action at Wembley Stadium, and a brief stint at Twickenham, NFL has a new London-home for the foreseeable future.
A year later then planned, Tottenham Hotspur's glittering new stadium is all set for its American unveiling this evening, as the Chicago Bears face the Oakland Raiders in the first of four NFL matches taking place in the capital over the next month.
But what is the deal between Spurs and the NFL? Why has all the fuss gone into creating a venue adaptable to two sports and surfaces? And what can we expect from Sunday's event as a whole? Sportsmail reveals all...
Why is the NFL in London?
The NFL (National Football League) has been coming to London since 2007, when the first 'International Series' match was played between the New York Giants and the Miami Dolphins at Wembley.
Since then, there have been a total of 23 matches in London, as the Series has expanded in regularity. From one game a season in 2012, there are now four games pencilled in every season.
But now, a new venue has been added to the mix. Tottenham Hostpur's £1billion, 60,000-capacity stadium, which officially opened in April, will host a minimum of two matches every season for the next 10 years as part of a lucrative deal between Tottenham Hotspur FC and the NFL.
How can the stadium host football and NFL?
From a logistical point of view, that's easy. The football club will simply not host any home games near to when NFL games are scheduled at the stadium. This year for example, Spurs played away to Brighton yesterday, and next week's game takes place during the international break.
But the real genius comes in the stadium design. The grass field used for Tottenham games is retractable, with an artificial turf used for NFL underneath.
This means the - at times - shocking playing surface at Wembley, which saw the turf quickly tear up, is a non-issue. Furthermore, there are dedicated NFL facilities intertwined in the background, such as the changing rooms, which are big enough to house a full NFL squad and support staff. There are also a raft of player facilities including hydrotherapy and medical areas.
As impressive as the myriad of features available now, the whole setup will undergo it's first proper test on Sunday.
Who's playing?
So tonight, the Chicago Bears face the Oakland Raiders in what is technically a Raiders-home fixture. Kick-off is at 6pm.
Next Sunday, at the earlier time of 2:30pm, the Carolina Panthers play the Tampa Bay Buccaneers in an NFC South match-up.
The final two games of the London Series take place at Wembley. First, the Cincinnati Bengals play the Los Angeles Rams on Octover 27, and a week later the Kansas City Chiefs face the Los Angeles Chargers in an AFC West tussle.
Who are the favourites tonight and why?
After reaching the play-offs last year and coming within inches of a divisional game, the Chicago Bears are undoubtedly favourites against a Raiders-franchise who had a 4-12 record last year, finishing rock bottom of the AFC West.
But, it is far from a foregone conclusion. The Raiders, coached by the charismatic former pundit Jon Gruden, are currently 2-2 and won impressively on the road at the Indianapolis Colts last week. Quarterback Derek Carr threw for two touchdowns, and is seemingly finding some confidence as the season hits full swing.
For the record, Gruden can also coach in the knowledge he is virtually un-sackable at the moment - he is just one year into a 10-year contract with the organisation. Alan Pardew, eat your heart out.
This week will be an all-together sturdier challenge though, with the Bears defence one of the strongest in the NFL. Pro Bowl pick Khalil Mack (who was traded by the Raiders last summer) is a devastatingly effective pass-rusher, and with defensive end Akiem Hicks likely to return, Carr will have to release the ball quickly and efficiently.
On the flip side, the Bears offence is struggling, so much so that starting quarterback and first-round 2017 draft pick Mitchell Trubisky is likely to be dropped for backup Chase Daniel. Daniel completed 22/30 passes thrown when he came on in last week's win against the Minnesota Vikings, so is more than capable of stepping in.
What do players and fans think of the stadium?
The professionals who visited the stadium in July for the unveiling of the inaugural NFL Academy were distinctly wowed by what they saw.
Hicks observed: 'I think it's awesome. It has a very modern feel to it.
'The first thing that I noticed was it doesn't seem like there's a bad seat in the house. Everybody can be close to the game and engaged. I thought the cockerel on top was a pretty nice touch.'
NFL poster-boy Odell Beckham Jr, now at the Cleveland Browns, said: 'It is a big locker room. I won't lie to you. It's very nice though. It's better than the facilities we have back home to be honest with you or at least the ones I've been in.'
The standard has been set, it seems.
Any half-time entertainment?
Absolutely! British rapper AJ Tracey will stage the first-ever NFL London Games half-time show when he performs tonight.
After headlining at Glastonbury and selling out at Alexandra Palace, Tracey will now play at the home ground of Tottenham Hotspur, the football team he supports.
Could the stadium host a London franchise in the future?
It's been mooted for years, and there are no concrete signs yet that the NFL are planning to expand to London in the near-future.
However, given the long-term nature of the deal the NFL has in place with Tottenham, should a London-franchise get off the ground, Spurs' stadium would be the obvious front-runner to host the organisation.
One step at a time though. First, it has to pass the test of this evening's highly anticipated curtain-raiser.
