if you go to http://jermaintaylor.com and scroll down, you will find this tidbit:

"It is likely that when the rematch takes place it will again be a 160-pound title fight, and not at a 166-pound catchweight as originally written in the contract.

When the contract was signed, Taylor believed he would no longer be fighting at middleweight if a rematch took place. However, because he had such little problem making 160 pounds this time around, it appears he might be able to stay in the middleweight division, after all."
