Ryan Day

Ryan Day is an American football coach and former college player. He is the 25th and current head football coach at the Ohio State University.

Day was the offensive coordinator for Temple in 2012, as well as the offensive coordinator for Boston College from 2013 to 2014. He was hired as the Philadelphia Eagles' quarterbacks coach on January 22, 2015. Then, in 2016, after his mentor Chip Kelly was relieved of his duties in Philadelphia, Day was hired in the same role by Kelly, who became the head coach of the San Francisco 49ers. On January 3, 2017, Day was hired to replace co-offensive coordinator Tim Beck of the Ohio State Buckeyes. After being linked to the Tennessee Titans offensive coordinator position in January 2018, Day was promoted to offensive coordinator and primary playcaller at Ohio State.

On August 1, 2018, he was named acting head coach at Ohio State when head coach Urban Meyer was placed on administrative leave after alleged domestic violence incidents against then-fired assistant coach Zach Smith were made public, winning all three games during Meyer's absence.

On December 4, 2018, Ohio State announced that Meyer would retire as head coach after the 2019 Rose Bowl and be replaced by Day on a full-time basis. This will be Day's first full-time head coaching job.
