The Pro Football Hall of Fame announced it could induct a one-time only class of 20 members next year to further commemorate the NFL’s 100th anniversary. The class will include five modern era players, 10 senior era players, three contributors and two coaches.

The decision was approved by the Hall’s Board of Trustees during its annual meeting Friday.

The next decisions will be announced in September as a large list of nominees in each category will be revealed.
