Joshua Buatsi will look to close in on a maiden world title shot when he collides against London rival Craig Richards.
Buatsi - under Virgil Hunter - is aiming to challenge one of the light heavyweight titleholders and he could even face Canelo Alvarez at the end of the year if he plays his cards right.
However, one fighter stands in the way and that is Richards - the same fighter who took Dmitry Bivol - Canelo's next opponent - the full distance last year.
Below, we take a look at all of the information ahead of fight night.
When and where is the fight?
Saturday, May 21 at London's O2 Arena.
What channel is Buatsi vs Richards on?
The whole card is live and exclusive to DAZN worldwide.
What's on the line?
No titles but there is more on the line than just London pride. Buatsi is ranked inside the top five of three organisations (WBA, WBC and IBF). A victory for either man will see them close in on a world title shot.
What have they said?
Buatsi: "I wouldn't dub it as the hardest test, for me, it's just the most important fight in my career right now. It's the next fight, the fight I must win, last time with Bolotniks but this time it's Spider. I'll prepare as diligently as I do, come May 21 I'll be ready.
"I have to thank Matchroom and Spider's team, also my team, for making this fight happen. Fighters can tend to wait for the opportunity, for me currently it's looking a bit tricky, but I've got a good fight and that's what I'm concentrating on.
"I think that [Canelo] makes this a big fight for me, makes it even more important. I know what is at stake, what the reward is and that's what I said when I was in Arizona. I'll fight these guys as long as I know what's next. This may lead to a world title fight next so for me, I'm easy, no matter who it is I'm prepared."
Richards: "We're two top tier fighters from the UK. This is one of the biggest London domestic clashes for a long time. This is a very exciting fight for us both, but also one the fans will enjoy.
" Buatsi has got his plans and I'm sure he be well prepared, but nobody is going to stop me from fulfilling my destiny of becoming a world champion!
"He is a solid competitor and will be coming to win, but I am confident and believe I have the tools to get the job done. I proved myself at world level and I'm eager to prove that's where I belong."
Who is on the undercard?
Alen Babic will look to keep his destructive knockout streak going when he takes on Adam Balski for the vacant WBC Silver bridgerweight title.

Catford's Ellie Scotney (4-0) was made to work hard as she battled past Jorgelina Guanini to earn the WBA Intercontinental super bantamweight crown at the famous Alexandra Palace in February. She puts that belt on the line against Argentina's former world champion Maria Cecilia Roman (16-6-1).
