Justin Manning rejoined the Duke coaching staff in February of 2021 and serves as the special assistant to the head coach and defensive quality control. Manning spent the 2017-19 seasons on the Blue Devil coaching staff as well serving as a football operations assistant working primarily with the defense.
Manning returned Durham after serving one year as the defensive line coach at Eastern Illinois University.
During his previous stint at Duke, Manning helped the Blue Devils to two winning seasons and two bowl game appearances at the 2017 Quick Lane Bowl and the 2018 Walk-On’s Independence Bowl. While with the Blue Devils, he worked closely with All-America linebacker Joe Giles-Harris and All-ACC tackle Mike Ramsay.
Manning spent the 2016 season as a cornerbacks coach at Tufts University, helping the Jumbos to a 7-1 record, the program’s best record since 1998. Including
the Jumbos’ 6-2 finish in 2015, the 13 wins in the two seasons were the most for Tufts since 1979-80.
Tufts’ defensive unit held foes to 18.9 points per game and just seven rushing touchdowns during the campaign. Sophomore cornerback Tim Preston was selected to the New England Small College Athletic Conference First Team after leading the league with five interceptions, highlighted by a 99-yard return for touchdown against Colby College.
Manning spent the summer of 2015 as a coaching intern with the NFL’s San Diego Chargers, where he assisted with the daily preparation of the tight end unit, served as quality control of the two-minute offense and handled statistical analysis and film breakdown of opponents’ two-minute offenses.
Prior to his summer stint in the NFL, Manning served the 2014-15 seasons in a variety of roles at Boston College. He was an assistant recruiting specialist, special teams assistant and assistant running backs coach during his time with the Eagles. While at Boston College, Manning worked with All-ACC running back Jon Hilliman.
A native of Raleigh, Manning graduated from North Carolina Central in 2011 with a degree in business administration and was a four-year letterwinner (2008-09-10-11) as a fullback with the Eagles. He earned a master’s degree in criminal justice from Fayetteville State University in May of 2014. He currently resides in Durham with his wife Madi and their son, Jyonel.
