Jaguars head coach Mike Mularkey has named three assistant coaches to his staff, including former Jaguars offensive line coach Andy Heck. Josh Hingst was named assistant strength and conditioning coach, and Charlie Skalaski was named assistant to the head coach/offensive assistant.

Heck is a veteran of 20 seasons in the NFL, with a career that includes 12 years as a player and eight in coaching. During Heck's tenure the Jaguars have posted the three highest single-season rushing totals in franchise history along with two of the three lowest figures for sacks allowed.

This is Heck's seventh season as the Jaguars' offensive line coach and his ninth season on the Jaguars staff. He joined the Jaguars in 2004 as the offensive assistant/assistant offensive line coach, and spent the 2005 season as Jaguars assistant offensive line coach before being promoted to offensive line coach in 2006. Prior to joining the Jaguars Heck served three seasons on the University of Virginia coaching staff.

Hingst served the past three years as the director of sports nutrition at Nebraska after spending the 2008 season with the Atlanta Falcons. In his role at Nebraska Hingst directed body composition analysis, nutrition education, performance fueling strategies, eating disorder prevention and counseling for sports supplements and hydration.  In addition, he coordinated menus and education at the Nebraska training table and planned meals on the road for various Nebraska teams.

Hingst is a registered dietician and a certified strength and conditioning specialist.  Prior to his stint at Nebraska, Hingst served as team nutritionist for the Atlanta Falcons during the 2008 season.   He also spent five years in strength and conditioning and sports nutrition capacities at Florida State.

Skalaski previously served nine seasons (2003-11) as an assistant at Liberty in a variety of capacities. After coaching the tight ends for Liberty in 2003, he served eight seasons as wide receivers coach, while also serving as the program's director of football development from 2003-05. He was named recruiting coordinator in 2006 while continuing his role with the wide receivers. 

Skalaski began his coaching career as a graduate assistant at Florida, where he spent three years learning under Mike Shanahan and Steve Spurrier, assistant coaches for the Gators during that time. A native of Miami, Skalaski played defensive back at Florida and was a member of three bowl teams: 1974 Sugar Bowl, 1975 Gator Bowl and 1976 Sun Bowl.
