Bob Robertson, who was in his 52nd season on the Washington State football radio broadcast, announced he will retire immediately.
Robertson began calling Cougars games as the play-by-play announce in 1964 and remained in that role until sliding over to the analyst chair in 2011.
"I've been with the Cougars a lot of years, more than half a century, calling basketball, football for the fans around the Northwest and elsewhere around the country and I've enjoyed every minute of it," Robertson said in a statement. "It's been great to be with you Cougars at your meetings and get-togethers, and I hope we can do it again and I'm sure we will.
