With less than a day until National Signing Day, the Arizona State Sun Devils have yet another vacancy to fill on their coaching staff. Defensive line coach Jackie Shipp has accepted the same position at The University of Missouri, according to SunDevilSource and Burns and Gambo.

DL coach Jackie Shipp is leaving ASU for same job at Missouri per a source. Believe this was first reported by @BurnsAndGambo — SunDevilSource.com (@SunDevilSource) February 1, 2016

Shipp has been the defensive line coach at ASU since 2013 after spending the previous 14 seasons in the same position at Oklahoma, his Alma Mater. While at Oklahoma, he coached future NFL players such as Tommy Harris and Gerald McCoy.

Shipp's units have consistently been some of the strongest since his arrival at ASU and he has aided in players such as Will Sutton, Davon Coleman and Marcus Hardison, moving on to the NFL.

In 2014, ASU finished with 39 sacks, which was 13th nationally and in 2013 defensive tackle Will Sutton won Pac-12 Defensive Player of the Year.

If Shipp does leave, he would be the fifth coach who started training camp and is no longer on staff. Bo Graham was let go in the preseason and Mike Norvell, Chris Ball and Chip Long are all at Memphis.

Todd Graham is expected to speak to the media tomorrow at ASU's annual signing day press conference and we will update this story as more details become available.
