Knight was born in Fairmont, West Virginia the third child and son of James A. and Olive Knight, and attended nearby West Virginia University where he was a cheerleader and law student. He wrote a pep song, "Fight Mountaineers," which is still frequently used by the Mountaineer Marching Band 90 years later. He also wrote the melody for a WVU song entitled "To Thee Our Alma Mater," with words by fellow graduate David A. Christopher. He formed his own band in college and played drums, eventually leaving school to perform in vaudeville and in big bands such as Irving Aaronson's and George Olsen's. Eventually his musical and comedy skills took him to New York, where he appeared in Earl Carroll's Vanities of 1927 and on Broadway in Here's Howe and Ned Wayburn's Gambols. He was billed under his nickname, Fuzzy (given him because of his peculiarly soft voice).

While touring with bands, Knight came to Hollywood and appeared in several musical short films for MGM and Paramount between 1929 and 1932. Mae West gave him his first notable film role in She Done Him Wrong, and he went on to play in hundreds of films over the next 30 years. By the 1940s, he was primarily playing in Western movies and was voted on of the Top Ten Money-Making Stars in Westerns in 1940.

Knight became famous to a new generation when he co-starred as Buster Crabbe's sidekick on the 1955 TV series Captain Gallant of the Foreign Legion. In semi-retirement thereafter, Knight continued to make occasional appearances in films and TV shows through 1967.

He died in his sleep at the Motion Picture Country House and Hospital in Woodland Hills, California, and was survived by his wife, actress Patricia Ryan (née Thelma de Long). He was buried in Valhalla Memorial Park Cemetery in Burbank, California. His unmarked grave is next to that of the grave of Slapsie Maxie Rosenbloom, Knight's two-time co-star, who died less than two weeks after Knight.
