Heisman winner Kyler Murray will not play in both the NFL and the MLB, according to The San Francisco Chronicle.
The Chronicle reports that Murray will have to pick one sport "because the demands of learning and playing quarterback in the NFL would preclude him from playing professional baseball."
Murray has until Sunday to declare for the 2019 NFL draft.
Murray played both sports at Oklahoma and won the Heisman Trophy this season. He led Oklahoma to a 12-1 record and a berth in the College Football Playoff by throwing for 4,053 yards and 40 touchdowns.
