The sportscasting profession has lost another one of its greats - the legendary Keith Jackson has passed away at the age of 89.

Jackson retired back in 2006. For years he was the voice of college football broadcasts. His folksy phrase ' Whoa Nellie' he used to describe great plays became one of signature calls.
He is also credited for nicknaming the Rose Bowl 'The Granddaddy of Them All' and nicknaming the Michigan Stadium 'The Big House'.

Jackson began calling college games for ABC television in 1966. He also worked NFL and NBA games. He called World Series and Olympic games.

Jackson's death is the second loss of sportscasting greats in recent weeks. Dick Enberg died just a month ago at the age of 82.
