High Quality Content by WIKIPEDIA articles! The 2011–12 KHL season was the fourth season of the Kontinental Hockey League. The regular season began with the Opening Cup game on 7 September 2011, but because of the 2011 Lokomotiv Yaroslavl air disaster, which occurred during the first period of the Cup game and killed all but one member of the Lokomotiv Yaroslavl team, further play was delayed until 12 September 2011. The tragedy forced Lokomotiv Yaroslavl to cancel their participation in the KHL season. The Opening Cup was renamed the Lokomotiv Cup in honor of those lost in the tragedy. The regular season ended on 26 February 2012 and the following playoffs ended on 25 April.
