It's an Alien Perspective, perhaps:

Tons of trained muscle wait by the field 
sheathed in armor and prepared 
for One More Battle.   There are no weapons 
in this trial of Brute Strength and Cunning.
       Totemic emblems and colors displayed, 
two mercenary bands contend for possession of one 
ovoid leather ball, twice the victim.
                              Once as beast, 
sacrificed for its hide, 
mutilated by knives and needles to take this form 
and again, this day kicked
             thrown and carried into danger by those intent
                                          upon their goal. 

The competition begins, ringed by onlookers
roaring encouragement 
                               but not for the ball.
