Santos had Manuwa in all sorts of trouble not long into the bout, after cracking him with a big shot. Manuwa managed to recover, however, and both light-heavyweights proceeded to land thumping strikes in several, ensuing exchanges.
In round two, both men came out winging vicious shots again, but Santos tagged Manuwa with a huge uppercut and a follow-up hook that finished the wild slugfest.
