For Round 4 of our 12 Rounds of Christmas, we turn our attention to a couple of hammer-fisted boxers who put the heavy in heavyweight.
Chris Arreola and Curtis Harper each tipped the scales in excess of 260 pounds in advance of their March 13 rumble in Ontario, California.
As sturdy as the canvas was that held Arreola and Harper upright, the chins of the two boxers proved even sturdier-especially in Round 4.
Harper, who rose from a first-round knockdown, landed a slew of crushing blows in the fourth, but Arreola-putting aside the pain from an obviously injured right hand-gave as good as he got.
And although neither fighter was in serious danger of hitting the deck in the round, that was more a testament to each guy's ability to take bone-crushing punches.
Following eight rounds of two-way, welt-raising punishment, Arreola was declared the winner by unanimous decision.
Needless to say, it was a victory that left a mark.
