Allan Shields played in the longest game in NHL history. Montreal Maroons vrs. Detroit Red Wings, March 1936. In 1934 he was selected to the First NHL All-Star Team ever assembled. As an interesting side note, in 1930/31 he along with Syd Howe and Wally Kilrea were loaned from Ottawa to the Philadelphia Quakers to help liven up the team and attract more Quaker fans. Philly was in bad financial shape at the time and needed greater attendance to survive. With the assistance of Shields and company their games became “quite exciting”, culminating with a Christmas Day game when the entire Philadelphia police force were called to quell a near riot. With the onset of the Depression, the team folded the following year. The Quakers set another near NHL record for games lost, however they were one of the more “lively” teams of the time. On a couple of occasions during his career, he had to fill in as a goalie. In those days no spare goalie was available and if the one and only was injured during a game one of the players had to fill-in.

Allan Shields played in the American Hockey League (the primary farm teams of the NHL) for the Washington Lions, Buffalo Bisons and the New Haven Eagles from 1938 to 1942. He served as playing coach for Washington and then enlisted in the RCAF. Shields was selected to All-Star teams twice during his AHL career During his service in the airforce he was playing coach for the RCAF Sabres stationed in Arnprior, Ontario. After the war, “Big Pete” went on to Referee in the AHL from 1946 to 1948 and then hung up his skates permanently. He played a total of 457 game in professional hockey in the days when bus and train were the only means of transport. Allan Shields was reported in the media at the time, as “a clean, rugged player” and “one of the most valuable defensemen in the entire league”. King Clancy who was best man at Shields’ wedding, had nothing but praise for Allan’s ability as a defenseman.
