The United States trainer who knocked himself out with chloroform in 1930

During the 1930 World Cup semi-final between the United States and Argentina, the north Americans were taking a kicking in more ways than one.

They would go on to lose the match 6-1, but it was also a ferocious match with numerous poor challenges flying in.

One particularly bad tackle required USA trainer Jack Coll to enter the pitch to give some treatment. As he trotted onto the grass he dropped his medical bag, and in doing so, broke a container of chloroform.

The fumes knocked him out, and as a result it was he, rather than the player he went to treat, that needed carrying off the pitch.
