When he did, it was lights out for Rock. Coffie went to work in the third round, dropping Rock with a left uppercut. Rock was able to make it to his feet to beat the count of referee Jack Reiss. A few seconds later, Coffie clipped Rock again with a short left hook that sent him to the canvas a second time.
