"Wolgast, the snarl of the battle on his lips, a vertable ring demon, was forcing Rivers in front of him along the ropes on the north side of the ring. Lashing out, the champion sent a right to the body and followed with a low left to the belt territory. Rivers crashed to the floor under the crushing assult, and the force of the delivery carried Ad toppling over on top of the Mexican.
     Simultaneously both men claimed a foul. Wolgast struggled wearily to a sitting position and threw both gloved hands to his abdomen claiming that River's had kneed his groin. Laying at full length on the canvas, the brown challenger clutched at his belt line with both hands, while his frantic seconds set up a succession of shrieks to the effect that the blow which floored the Mexican boy had been a low one delivered in foul territory."
