Alabama star wide receiver Calvin Ridley is entering the NFL Draft, sources told AL.com.

In three years with the Crimson Tide, Ridley caught 224 passes for 2,781 yards and 19 touchdowns, including 63 catches for 967 yards and five touchdowns this season. Ridley, who is widely expected to be a top-15 pick in the draft, scored the game-tying touchdown in the fourth quarter to help send the CFP national championship game to overtime.

After this story was published, Ridley confirmed the news with an announcement on Twitter.

"Preparing for a life after college football, regardless of what your future may hold, can be a scary proposition for many athletes especially those who DID NOT attend the University of Alabama," Ridley wrote. "Having been thoroughly prepared for that next step, I am truly ready, because in the beginning, I chose THE RIGHT SCHOOL."
