The Eagles filled an important vacancy on Thursday, hiring Boston College offensive coordinator Ryan Day as their quarterbacks coach.

Day, who has coached at Boston College for nine season, replaces Bill Musgrave, who was hired by the Oakland Raiders earlier this week.

With the hiring of the 35-year old Day, head coach Chip Kelly will have a new quarterbacks for the third time since entering the NFL.

Day got his coaching career started at the University of New Hampshire in 2002 under Kelly as a tight ends coach. He was also Kelly's quarterback from 1999-2001.

From there, Day bounced back and forth between Boston College, Florida, and Temple University, coaching at all three schools between 2003 and 2014.

Day coaching at all three schools over that time frame had more to do with Steve Addazio than performance, as Addazio went from Florida to the head coach of Temple before then moving to Boston College.

In his 11 year coaching career, Day has coached tight ends, wide receivers and quarterbacks.

Here is more information on what Day accomplished during his time at Boston College, according to the team's official website.

• Orchestrated an offensive attack that yielded an average of 27.7 points per game - the program's highest average since the 2007 Eagle entry averaged 28.3 points per game en route to an 11-3 record

• Coordinated the Eagle run attack to an average of 212.5 yards per game, a mark good for second in the Atlantic Coast Conference and 20th among all teams in college football in 2013; the average was a 121.5-yard spike from the previous season's average, marking the largest one-year improvement in ACC history

• Directed the Eagle offense to a 96.9 percent red-zone conversion rate in 2013, a mark good for second among all programs in the nation; team scored on 32-of-33 trips into the red zone

In his final season at Boston College, Day's quarterback was Tyler Murphy, a dual-threat passer who totaled 1,623 yards passing, 13 touchdowns, 10 interceptions to go along with 1,184 rushing yards and 11 touchdowns.

With the hiring of Day reportedly done, the Eagles now can focus solely on their other vacancy — general manager.
