It is through its relationship with Boxxer that bet365 was able to secure this betting partnership for the fight.
A bet365 spokesperson said: “Live on Sky Sports and brought to you by our partners at Boxxer, we’re thrilled to be part of this huge night of British boxing.
“It’s going to be an explosive night on January 21st, and bet365 has you covered with a huge selection of pre-fight markets. Once the bell rings, our industry-leading In-Play product will take centre stage, with live odds and bet boosts throughout.”
The operator has Eubank Jr as the 4/11 favourite to win the fight, with Smith the 11/5 outsider.
The showpiece event’s undercard features matchups including Joseph Parker vs Jack Massey, Frazer Clarke vs Kevin Espindola and Richard Riakporhe vs Krzysztof Glowacki.
Per its partnership deal for the fight, bet365 branding will appear “prominently” across the fight’s pre-promotional activity, including at press conferences, open workouts and weigh-ins.
The operator will also have branding featured across all four ring corners, ropes and toblerones. It will also have digital advertising on the venue’s screens, banners and boards.
The deal further cements bet365’s partnership with Boxxer, with the operator remaining heavily featured across the promoter’s digital and social content.
In the lead-up to the fight, Boxxer will also showcase bet365 odds on its site, offering in-play optimisations exclusive to visitors of its website.
In return, bet365 with stream Boxxer’s content in select international territories, in what it hopes will “enhance the customer experience” of its offering across the globe.
