December 15, 2019.
On that Sunday, former Oklahoma quarterbacks Baker Mayfield and Kyler Murray will square off in a regular season matchup between the Cleveland Browns and Arizona Cardinals in Glendale, Arizona.
Mayfield and Murray last played on the same field together in the 2018 Rose Bowl, back when Murray was Mayfield's backup.
In the year and four months since that game, Mayfield became the first overall pick to the Cleveland Browns in 2018 and Murray became the first overall pick to the Arizona Cardinals in 2019.
Both quarterbacks won the Heisman Trophy award and helped carry the Sooners to College Football Playoff appearances.
