ROUND 1 - Soto opens southpaw and McDonald orthodox. Right hand from McDonald finds the mark, but Soto is unfazed. Now a left from McDonald. A monster right hand from McDonald nails Soto and drops him to the mat. Soto recovers briefly and even tries to stand, but McDonald is all over him. Soto backs his way into cage and a few more stikes render Soto totally unconscious.
The reply shows McDonald slightly ducking and firing a right hand as a counter to an inside leg kick from Soto.
