Big shot in round 4 sends Nicklow down hard...he stuggles up all bloody...Nicklow is a spent shell and Guerrero going in for the finish...things breaking off and ref takes a tumble haha...Nicklow on ropes soaking up uppercuts..Nicklow refuses to go and lands his own but wilting....ref steps in along ropes and waves it off...Guerrero straight pressure after calm start but leaky defense....Nicklow all balls but not enough fire power in end.
