Along with Humphrey, Hickman accepted a football scholarship from
Baylor University, where he majored in Business with a minor in Vocal Performance. He lettered for the Bears from 1955–58, earning all-Southwest Conference honors in 1958. He was named a member of the Baylor football all-1950s team and was inducted into the Baylor Hall of Fame in 1973. Hickman married the former Shirley Winn of Gladewater while attending Baylor. During the
1957 Sugar Bowl, Tennessee guard Bruce Burnham and Baylor guard
Charley Horton "got into a scuffle" on the ground. Burnham punched Horton a few times. Hickman then responded by kicking Burnham in the face, which sent him to the hospital. A doctor stated "I thought the boy would be gone before we got him off the field". Hickman was ejected and spent the rest of the game crying on the bench. He later apologized to Burnham in the hospital. ==Professional football career==
