12 rounds.
1st bout at 135.
2nd bout at 140.
Neutral location for both bouts.
This seems like it'd make a Great bout,especially at 135,where I see it as a 50-50 bout.
At 140, I think that Holliday would likely win by a close hard fought decision.

Haugen Ud. Haugen would outwork Holiday in both

Holiday decision
If Holiday played it safe and employed a strict defence he could likely win a UD.

The hard little South African wins it.....very physical lad, Mitchell level work-rate and a hungry/disciplined fighter.
Like Mitchell - the lack of a truly venomous punch - was the only thing missing.
Has more than enough to deal with Haugen I think.
