Internet star KSI will gift his former boxing coach Viddal Riley £10,000 if he can win his fight by knockout this Saturday.
Riley will make his long-awaited return to the ring on the undercard of Amir Khan's grudge fight against Kell Brook at the AO Arena in Manchester.
The Brit hasn't fought in almost two years due to several injuries and the Covid-19 pandemic delaying his ring return.
Riley had been scheduled to fight at a Gervonta Davis event in 2019 and on the undercard of Mike Tyson vs. Roy Jones Jr, but a back injury forced him out of both contests.
But after signing a multi-fight deal with Boxxer last November, Riley's return against Willbeforce Shihepo could be even sweeter if he wins by knockout.
"Knock him out and I give you 10k," KSI wrote to his former trainer Riley on Instagram.
Riley helped coach KSI for his two fights against fellow YouTube star Logan Paul, with both fights selling over one million buys on pay-per-view.
And Riley revealed he was also supposed to fight last June on the undercard of Floyd Mayweather vs Logan Paul.
"I made the right decisions," he told Mirror Fighting . "Some of the fights that didn't come through were no fault of mine.
"It was just the world changing, how to get around restrictions, I was supposed to be on the Floyd Mayweather vs Logan Paul card and I was ready to go, my team wanted me to go.
"But it wasn't down to me, the things that needed to be in place - I had done before during the pandemic but during a camp it ruins your flow."

Riley's opponent Shihepo fights in the UK for the second time, being knocked out by Callum Johnson in 2016 in their Commonwealth title fight.
The 39-year-old Nigerian has only fought four times in the last four years, losing three of those fights by stoppage.
And Riley feels an undercard spot on a big event such as Khan vs Brook is an opportunity he deserves.
"I am very thankful to the team over at Sky and Boxxer," he added. "They've brought me back for my UK debut on this show.
"I feel like that's the platform that I deserve, as much as I haven't been in the ring for a couple of years I've spent a lot of time building a great brand, and this is the time to showcase that brand.
"I'm excited to deliver a great performance in the ring. I'm having to get my family to help me telling people that we can't get them tickets for every fight."
