Murray is a projected first-round pick in April's draft and will nearly certainly become the first athlete to be drafted in the first round of both the National Football League and MLB.
Oakland drafted Murray with the ninth overall pick last June.
Kyler Murray will follow his heart, choosing to play pro football rather than baseball.
"Football has been my love and passion my entire life", Murray said in Monday's statement. "Kyler Murray would make a lot of sense in that situation given that Miami loved Baker Mayfield previous year". Additionally, Murray began his college career at Texas A&M - there and in the past three years at Oklahoma he played in variations of the Air Raid offense run by Kingsbury. "I was raised to play QB and I very much look forward to dedicating 100% of myself to being the best QB possible and winning NFL Championships".More news: Methanol-laced bootleg liquor kills at least 39 in India

Outfielder/quarterback Kyler Murray, this year's Heisman Trophy victor but also the No. 9 overall pick by the Athletics in the 2018 MLB draft, announced today that he will pursue a career in football rather than baseball (Twitter link). "I eagerly await the opportunity to continue to prove the National Football League decision makers that I am the franchise QB in this draft", Murray wrote.
Before Murray announced his decision Billy Beane, Oakland's executive vice president of baseball operations, acknowledged his team might lose the player. "The situation is fluid right now and based on a historic college football season that the young man had".
In October, first-year Cardinals coach Kliff Kingsbury suggested as Texas Tech's head coach that he would take Murray first overall in the upcoming draft.
