There has been alot of fights with low blows. Tito hit Vargas low, and maybe they were on purpose, but Tito had been going to the body all night, and those were more questionable than Zab's. Plus, Tito was losing some rounds, but wasn't in trouble like Zab. And, Vargas, IMO, purposely thumbed Tito in the eye. Paybacks suck!

Zab's punch wasn't as bad as the shat Derrick Gainer pulled, but looked that way because he had lost 5 rounds straight, and was getting hurt to the body.

I wouldn't DQ Zab for it, but when you're getting beat, and you've only landed a few body shots{mostly to the sides}, it looks kind of obvious that you purposely did it.
