The Hall was established in 2009 to honor the best players and coaches from historically black colleges and universities.
Dent, who played at Tennessee State and starred in the NFL with the Chicago Bears, was joined on the inductees list by Roger Brown, L.C. Greenwood, Ernie "Big Cat" Ladd, Ken Riley, Donnie Shell and former Jackson State coach W.C. Gorden.
The seven will go into the Hall on Feb. 28. They were selected by a 13-member committee of journalists, commentators, historians and former NFL executives.
Dent was a defensive end at Tennessee State and played 15 seasons in the NFL, with the Chicago Bears, San Francisco 49ers, Indianapolis Colts and Philadelphia Eagles. He was a five-time All-Pro and was inducted into the Pro Football Hall of Fame in 2011. Dent was MVP of Super Bowl XX with the Bears.
Gorden coached Jackson State from 1977-91, and guided the Tigers to eight Southwestern Athletic Conference championships. He was 118-47-5 with Jackson State.
That brings the number of inductees to 58. Among those already enshrined are Grambling's Buck Buchanan, Mississippi Valley State's David "Deacon" Jones, Bethune-Cookman's Larry Little, Alcorn State's Steve McNair, Jackson State's Walter Payton, Mississippi Valley State's Jerry Rice, Alabama A&M wide receiver John Stallworth, Texas Southern defensive end Michael Strahan and Grambling coach Eddie Robinson.
