Switzer knew of Dixon’s upcoming honor but couldn’t share the news.
Dixon was a consensus All-American in 1987, the same year he became Oklahoma’s first Jim Thorpe Award winner.
Dixon had nine interceptions as a senior, a single-season school record that still stands.
In that season’s 17-7 win over No. 2 Nebraska, Dixon had two interceptions, the second of which helped seal the top-ranked Sooners’ win and send OU to the Orange Bowl.
He finished his career No. 2 all-time in interceptions at the school, behind only Darrell Royal, and set a record for career interception return yardage. That record was later broken by Derrick Strait.
Dixon will be the fourth player from the Sooners’ 1985 national championship team to be inducted into the hall, joining Keith Jackson (2001), Tony Casillas (2004) and Brian Bosworth (2015). Switzer was also inducted in 2001.
Dixon was the No. 5 overall pick by the Cincinnati Bengals in the 1988 NFL Draft and played six seasons.
He was diagnosed with ALS in 2013.
