We just added another article, this one from 1911 ...
Some entertaining facts have been divulged in the negotiations for a match between Mahmout, the Turk, and Zybysko, the Pole, and the most interesting is the fact that in the last three years there have been but three matches in Chicago that were on the square.
One was the Hackenschmidt-Gotch match, which as an exhibition was the worst ever seen. But it was honest. Another with a taste of squareness was the Mahmout-Americus contest, on fall of which was on the level. The other square bout is not exactly known.
According to Powell at prowrestling.net there is a rather large chunk of the 3D/MCMG match that was edited out in post. He was apparently in the ring a longer period of time post-injury than was shown last night on tv.
