The DMX vs Zimmerman fight isn't going ahead as planned anymore, and they certainly didn't get to the weigh-in stage, so I don't think any accurate figures for height/weight are available.
Interestingly, gossip website TMZ are reporting that some sort of Zimmerman fight might still be on the cards, but with a different opponent.
Apparently, the original fight was cancelled because Feldman, the original promoter, started receiving threats online
"Feldman withdrew from the fight yesterday after he said he was bombarded with threats. One Tweet said, 'Somebody should kill Damon Feldman's son and ask him would he put his son's killer in a celebrity boxing match.' "
However, a new promoter has now stepped up and is trying to negotiate a fight between Zimmerman and someone else...
