Report: Heisman Winner Kyler Murray Won't Play Both Football, Baseball

Murray has until Sunday to declare for the NFL draft.

Heisman winner Kyler Murray will not play in both the NFL and the MLB, according toThe San Francisco Chronicle.

TheChronicle 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. He also ran for 892 yards and 11 touchdowns. Oklahoma lost to Alabama in the semifinals. Last spring, Murray was a star centerfielder with a .296 batting average and 10 home runs.

He was the ninth pick in the 2018 MLB draft by the Oakland A's and was paid almost $5 million as a bonus. With an award winning-season, there's been speculation he'd stay a senior season. His agent, Scott Boras, has insisted that Murray is committed to playing professional baseball and will be in Spring Training with the A's in 2019.

Running back Bo Jackson and defensive back Deion Sanders played in both the NFL and MLB in the 1980s and 1990s.
