Our sources also inform us not to be surprised if former junior welterweight champion Vivian Harris opens up the telecast, possibly against Alvaro Aguilar. An official announcement is expected to be made early next week. Boxingtalk will continue to keep you updated, until then REMEMBER WHERE YOU HEARD IT FIRST! (10:20 PM EST)
