October. Battle of the light heavyweight interim world champions (Benavidez is the WBC interim champ with a single defense; Smith is the WBO interim champ as of his victory over Joshua Buatsi four months ago).
Smith looked good against Buatsi but he always seems to lose the big ones. I think Benavidez by decision is the likely outcome he will be to active for Smith.
Really good fight, should be a bit of a shootout but David is too strong and too fresh I think. Can see him stopping Smith late.
This is a great fight as a pre-fight for a big event, Benavidez is likely to win, but Callum-Smith is certainly not to be underestimated...
