According to an article by the Professional Football Researchers Association, Jackson played for the Boston Bulldogs in 1929.
Jackson, a teammate of Arnie Shockley's from Southwestern Oklahoma State University, used Archie's invitation to try out for Boston.
According to Jackson, he was disappointed when he didn't receive an invitation to try out for any professional team after playing college football.
[2] However, the biography on Arnold Shockley for the SWOSU Hall of Fame states that he played for Providence for four seasons.
In trying to clear up the mistake in identity of the players, Bob Carroll, also of PFRA, states that the real Jackson, under the alias Shockley, played for Providence, while Shockley, using Jackson's name, played for the Bulldogs.
