Former Dallas Cowboys quarterback Troy Aikman and perennial All-Pro defensive end Reggie White head a list of 25 semifinalists for the Pro Football Hall of Fame. The board of selectors chose them from a list of 112 preliminary nominees, the hall said Tuesday. A list of 15 finalists will be announced in mid-January. The class of 2006 will be determined at the selection committee's annual meeting Feb. 4 in Detroit, the day before the Super Bowl. The list of 25 will be reduced by mail ballot to 13 modern-era candidates. The list will increase to 15 finalist nominees with the inclusion of the two recommended candidates of the hall's seniors committee. This year, they are former Oakland Raiders coach John Madden, and former Cowboys tackle Rayfield Wright.
