Oklahoma quarterback and Heisman Trophy winner Kyler Murray has officially declared for the 2019 NFL Draft.

Murray had signed a lucrative baseball contract with the Oakland A’s prior to the start of the 2018 college football season. While he was initially expected to play just one season of college football and then pursue his career on the diamond, the quarterback is keeping his options open.

Monday was the deadline to declare for the NFL Draft. Murray made the announcement via Twitter.

“I have declared for the NFL Draft,” Murray wrote.

In order to keep his options open, Murray had to declare for the NFL Draft by the deadline. It doesn’t necessarily mean he’s skipping on his baseball career, but rather has bought some time to make a decision on which sport he wishes to pursue.

February, when spring training begins in baseball, is a more likely deadline for Murray to make a final decision on his future.

Murray threw for 4,361 yards and 42 touchdowns in 2018, leading the Sooners to a 12-2 record, a Big XII title and a berth in the College Football Playoff. He also rushed for 1,001 yards and 12 touchdowns.

Murray was the second straight Oklahoma quarterback to win the Heisman Trophy, following in the footsteps of Baker Mayfield, who won the award in 2017.
