text: what is the age of the oldest player to play in a world cup?   not sure of the oldest to play, but roger milla, of the indomitable lions of cameroon was the oldest to score a goal,  when he entered the game (i think against russia)  in the 1994 world cup held at stanford univ., in palo alto, ca. i believe he was 42.  it was an event i'll never forget. the entire stadium erupted when he scored.
