I don't have one, but in the run to the Browne fight he was 190.6lbs 30-days out, 183lbs 14-days out and 179.4lbs 7-days out - https://imgur.com/f7GaF6A I'd guess him at mid to high 180's on fight night.
He was just under 183 the day of his scrap with Koelling. As far as I know, that's the closest to fight time he's ever been weighed.
Cheers. Do you have a source, please? I'm not doubting you, I just like to keep a record of these things. Thanks.
It's on Youtube. I'd point you to it but I'm on my phone with limited connectivity. Just search for the one showing the entire match. I'm almost certain there used to be an HBO broadcast that showed it on the Tale of the Tape, but the TR team also reference it in the commentary. I just rewatched it last weekend so I know it's there. Will post with the timestamp later on if you can't find it. EDIT: This content is protected
Thanks mate, I appreciate you going to the trouble of doing that. @BCS8 - given you said you'd love to have a confirmed fight night weight of Beterbiev, at the very start of the Youtube video Quick Cash posted, the commentator states Beterbiev weighed just over 182lbs earlier that day, though no mention of what time earlier that day.
