Jason Witt hopes to rebound from a tough less learned against Bryan Barberena at UFC on ESPN 28 . Witt’s (18-7 MMA, 1-2 UFC) most recent outing at UFC Fight Night 183 in March saw him knocked out cold against Matthew Semelsberger in just 16 seconds . It wasn’t what he was hoping for coming off his first octagon triumph but also understands that’s how the cookie crumbles at times. There’s a positive to it, too, because Witt said it forced him to make major adjustments in his life when it comes to proper rest and self-care.
