In an unusual move, Cumulus Media announced today that it will air Sunday’s NFC Championship game between the 49ers and New York Giants on all six of its San Francisco stations.

On the AM dial, the game will be heard on KSFO 560, KNBR 680, KGO 810 and KTCT 1050. On the FM dial, Cumulus is putting the game on KFOG 104.5/97.7 and KSAN “The Bone” 107.7.

“This is the biggest 49ers game in 10 years, and to ensure that the broadcast will be heard by as many fans as possible, the Cumulus program directors got together and decided to air the game on all of our Bay Area stations,” KNBR’s operations director Lee Hammer said in a statement.

“We are unaware of any NFL team that has had this kind of support from its radio partner,” said 49ers Director of Broadcasting Bob Sargent.

All of the stations will begin SF 49ers presume coverage at 2:30 p.m. followed by the kickoff from Candlestick at 3:30.
