Goalie Don Keenan played one game for the Boston Bruins in 1958-59. Apart from his cameo in the big leagues he played most of his hockey at the Canadian university level.
Born in Toronto, Keenan started the 1955-56 season with the St. Michael's Majors before enrolling at St. Francis Xavier University in Antingonish, Nova Scotia. He played three years with the X-Men and enjoyed his finest year in 1956-57 when he led all AUAA goalies with eight wins and a 2.50 goals-against average in the playoffs.
Keenan was helping out with the St. Mike's team in 1958-59 when he was loaned by the school to the Boston Bruins to replace Harry Lumley for a game on March 7 at Maple Leaf Gardens. Keenan was informed of his evening's work at 5:25 p.m. and played well considering the lack of preparation. The Bruins lost to Toronto 4-1 and many people began to question the NHL's standby goalie system when an NHL team was forced to rely on a part-timer who was unprepared and under-qualified. Keenan played one more year at the University of Toronto in 1959-60 and then retired.
