The race to succeed Johnny Manziel at the helm of Texas A&M's offense is narrowing, as Matt Joeckel, Manziel's backup, announced this week he plans to transfer.

As a graduate student, Joeckel will be eligible to play in 2014. The brother of former Texas A&M offensive tackle Luke Joeckel, he completed 22 of 37 passes for 293 yards and two touchdowns in five appearances.
