Dean (Boomer) Molberg of Sportsnet 960 The FAN has apologized and so has the station, saying it was a misguided attempt at humour.
The suspension was announced in a note on the station's website Friday.
The station is also offering to make a donation to the Saskatchewan Roughriders' charity of choice.
In 1956, four Roughriders were killed in a plane crash near Chilliwack, B.C.
This Sunday, the Roughriders will take on the Calgary Stampeders in the CFL's West Division semifinal.
