The list of candidates to replace AJ McCarron as Alabama quarterback became shorter after freshman Luke Del Rio took to Twitter to announce his intention to leave the program.

Del Rio will strongly consider transferring to Oregon State, a source told ESPN.com.

Luke's father, Denver Broncos defensive coordinator Jack Del Rio, has a close relationship with Oregon State coach Mike Riley. The Beavers recruited Luke out of high school and offered him a scholarship, but he ultimately chose to walk on at Alabama instead.

Alabama's change at offensive coordinator, bringing in former USC coach Lane Kiffin after the departure of Doug Nussmeier, coupled with four-star quarterback David Cornwell enrolling early, could have played a role in Del Rio's decision to transfer.

The Tide must now figure out who will replace McCarron under center.

Blake Sims took the majority of snaps as McCarron's backup this season, but he's viewed primarily as a run-first quarterback with a so-so arm. He threw three interceptions during Alabama's final spring scrimmage and went 18 of 29 for 167 yards and two touchdowns during the season.

Alec Morris, a strong-armed redshirt freshman from Texas, was third on the depth chart. The former three-star prospect took some snaps but didn't attempt a single pass during a game this season.

Cooper Bateman, the third-ranked pocket passer in the 2013 class, and Parker McLeod, a three-star prospect from Georgia, both redshirted their first seasons on campus. They'll be joined by Cornwell in the quarterback competition this spring.
