Let's see how Dixon copes with this because this is a different mental challenge now to the ones she has faced before. Not just tactically but mentally, this is a tough place to be.

The experience is showing here. We feared it would, and it certainly is.

Dixon has to get close and let her hands go. What can happen with these quick rounds is you can be three or four rounds down and not feel like you're losing. She's got to let her hands go now.

It's small and intimate but there's something quite heartwarming about this arena.
I walked through the deserted Sheffield Olympic legacy park grounds until I stumbled across a small group of Matchroom security folk who I recognised. I waited in a reception which isn't too dissimilar to my local council-run leisure centre before I was taken to my seat.
I'd say it's a 20 yard walk from the fighters' entrance to the ring. We have three small seated areas on the ground and two stands which go about 15 or so rows back.
No need for screens; nobody here has a bad view.
Is this make or break for Terri Harper? She describes tonight's fight as the "last roll of the dice" but didn't go as far as to say whether she'd retire with a loss. I know, talk of retirement at 27 is madness!
But, Harper has not won since May 2023 and has since admitted she "lost the love for the sport" after her damaging loss to Sandy Ryan.
Whatever happens tonight, Harper has had a superb career in women's boxing.
