(This story appeared in today’s edition of USA TODAY .) SEATTLE – For most new parents, the first week after their child’s birth is one of great joy, a time to celebrate a new life and the growth of a family. For UFC flyweight titleholder Demetrious Johnson , that week will include a five-round prizefight with his belt on the line. “I’ve never gotten in the octagon, regardless of the circumstances, and not been in shape and prepared to fight,” Johnson told USA TODAY Sports and MMAjunkie.com (www.mmajunkie.com). “So I’ve made arrangements. It’s not like I was in the hospital eating chicken tenders and french fries. I’m going to handle my business as a married husband and take care of my responsibilities, but I’m also going to handle my business as UFC champion.” Johnson (17-2-1 MMA, 5-1-1 UFC), a Washington state native and resident, puts his 125-pound title on the line Saturday against top contender John Moraga (13-1 MMA, 2-0 UFC) in the headlining bout of UFC on FOX 8, at Seattle’s KeyArena
