Is this the interview where he say he wants to retire in 2 years, or will retire as soon as he's won all 4 belts? I'm in work so can't check and wanted to find that interview
No, this is the most recent interview. And the one you mentioned is here: https://www.boxingforum24.com/threads/an-interview-q-a-instagram-session-with-lomachenko.624449/
Initially there were concerns that those might be needed. But as it seems, the injury wasn't that serious — the doctors just put the joint back in place and put a cast on.
So before the fight Serge predicts that Loma might suffer a hand injury Then after the fight Serge predicts that instead of reverting back to Rival gloves, which is what I think he should do, Venum will make him a custom pair and that is exactly what Loma says has happened at the 1:06 mark of the video.
