(973espn.com) — Eagles first-year head coach Doug Pederson put the finishing touches on his inaugural coaching staff on Wednesday at the Senior Bowl in Mobile when he tabbed long-time college coach Chris Wilson to mentor the defensive line.

Wilson was set to coach the DL at the University of Missouri in 2016 before reversing course and heading to the NFL.

The veteran coach has a history with Philadelphia's best player, defensive tackle Fletcher Cox, as the Pro-Bowler's position coach and defensive coordinator at Mississippi State in 2010.

Wilson's 23-year sojourn at the college level began as a graduate assistant for Indiana State in 1993, just one year after being selected in the 12th round of the '92 NFL Draft by the Chicago Bears after a solid playing career at Oklahoma.

Wilson was a full-time coach by the next year with the Sycamores when he mentored the linebackers. From there he has stints with Northern Illinois, Northeast Oklahoma,  Indiana State again, and Illinois State before breaking in to his first big-time program at Colorado in 2000.

Since then Wilson has been a part of coaching the D-Line for some of the best programs in the country, including his alma mater Oklahoma, Mississippi State, Georgia and Southern California.

Wilson has also had NFL minority internships with the Dallas Cowboys ('95), Arizona Cardinals ('97) and Miami Dolphins ('98).

Philadelphia also named Joe D'Orazio as assistant wide receivers coach under Greg Lewis. D’Orazio spent last season at Columbia and had a history with Pederson under Andy Reid in Kansas City before that.
