Senior quarterback Keller Chryst announced his intention to transfer for his fifth year of eligibility on his Twitter account Sunday afternoon. He did not specify which which school he intends to transfer to in his announcement.

With sophomore KJ Costello seemingly entrenched as a starter for the next season, Chryst will graduate in June and then become a graduate transfer for a new program for the 2018 season.

Chryst played in 23 games and passed for 1,926 passing yards on 289 attempts with a 55 percent completion percentage over the course of his Stanford career. He took over for Ryan Burns in the 2016 season after the Cardinal suffered their third loss of that season to Colorado. Stanford would win the next six consecutive games leading to a victory in the Sun Bowl.

Chryst would tear his ACL in the Sun Bowl but he was healthy enough to start the 2017 season. After a game against Oregon State in which Chryst threw for 141 yards and one interception in a 15-14 win, Costello took over as starter for the rest of the year.

The best games of his career were played against Oregon. In 2016, he threw for 258 passing yards and three touchdowns in Eugene, followed by a home game against the Ducks in 2017, where Chryst matched his three touchdowns and had a 71.4 completion percentage.

Coming out of Palo Alto High School, Chryst was the No. 3 pro-style quarterback of the Class of 2014.

Now that Chryst is transferring, the quarterbacks on the roster for the White-Cardinal Spring game are Costello, Jack Richardson and Davis Mills.
