Al Pfeifer was one of the top receivers in the CFL, mainly with Toronto, in the early to mid 1950s.  Pfeifer joined the Toronto Argos in 1951, but then missed all of 1952 and most of 1953 due to military service back in the States. Pfeifer did play in 5 games in 1953 while on a furlough. Pfeifer returned full time in 1954 and remained with the Argos throughl 1956. Pfeifer then played one year with Ottawa in 1957 and retired. In October of 1958, Pefier came out of retirement to play for the London Lonrds of the ORFU..  There were no individual stats kept for Pfeifer's first  two seasons in 1951 and 1953, but had 68 catches for 1142 yards in 1954 which was the second best in the East.  In 1955, Pfeifer led the East in receiving with 75 catches for 1342 yards, and was named to the East All-Star team (there were no CFL All-Stars until 1962).  Pfeifer also led the East in scoring with 15 touchdowns and 23 converts for 98 points (TDs were still 5 points in 1955).  Pfiefer set a career high with 78 catches in 1956, though his yards dropped to only 993 yards, which ws good enough for second in the East in receiving.  With Ottawa in 1957 Pfeifer had 44 catches for 700 yards to finish third in the East in receiving.

Games played stats were not kept in the East until 1960. The all-time Argo roster in their media guides credits Pfeifer with 51 regular season games with the Argos and 4 playoff games.
