Jackson, who tipped the scales at 206.5 pounds, has two hours to lose the excess weight in order to get down to the contracted requirement of 205 pounds.
"The last organization I was with kind of sapped the love I had for MMA but it's starting to come back with Bellator. There are a few things I'm not 100 percent happy with," Jackson said of Bellator. "Some things are better than others and some things [Viacom] said they were going to do, I wished they'd worked out better. But Bellator itself, they treat me with respect. My relationship with Bellator, which is who I have contact with on a day-to-day basis anyway, the way the promotion and Bjorn Rebney treat me is with respect.
"There are a few things outside of their control that I want worked on that I'm not worried about now because I'm focused on my fight but I'm sure those guys will work on it and fix it for me when we do talk. My body is feeling good and I'm more excited to fight than I have been in awhile."
Since Jackson's fight isn't a title bout, he is allowed to weigh one pound over the 205-pound limit. In all likelihood, Jackson will be able to get down to 206 pounds on his second weigh-in attempt.
As for M’Pumbu, he weighed in well under the 205-pound light heavyweight requirement. M'Pumbu checked in at a lean 199.75 pounds, six and a quarter pounds under the maximum allowance.
