Joining Allen, who played for the Cowboys from 1994-to-2005, among the first-year eligible candidates are kicker Morten Andersen, safety John Lynch, tackle Jonathan Ogden, defensive tackle Warren Sapp and defensive end Michael Strahan.
There were also 27 semifinalists named including former Cowboys pass rusher Charles Haley. Haley has been eligible for the Hall of Fame for eight years and named a finalist three times. He played with Dallas from 1992-to-1996.
Former Cowboys coach Bill Parcells is also a semifinalist for the second time. Parcells coached New England, New York Jets and Giants and the Cowboys during his career. He coached Dallas from 2003-to-2006.
The 27 semifinalists will be reduced to 15 modern-era finalists. That list increases to 17 finalist nominees with the inclusion of the two candidates from the seniors committee.
The results of the modern-era vote to 15 finalists will be announced in January.
