Are you thinking of Doc Powers? He was a catcher for the Athletics who died as a result of an on-field collision with the wall in foul territory at Shibe Park in 1909. He suffered internal injuries, and died as a result of complications from the resulting intestinal surgeries. He was the first MLB player to die as a result of an on-field incident.
The second (and more famous/infamous) fatality as a result of an on-field incident was when Indians shortstop Ray Chapman was hit in the head by a pitch from Yankees pitcher Carl Mays in 1920.
To my knowledge, they are the only two MLB players to die as a result of something that happened on the field.
