Purdy is the second quarterback headed to Nebraska through the transfer portal. Casey Thompson announced his move from Texas on Jan. 7.
Purdy said in November he planned to leave Florida State. He played behind Jordan Travis and McKenzie Milton and appeared in one game. He played in three games in 2020, starting one.
Purdy was a 4-star recruit coming out of Perry High School in Glendale, Arizona, and originally pledged to sign with Louisville before flipping to Florida State.
