NCAA Division I-AA playoff bracket

Only the top four teams in the field were seeded, with the NCAA placing others teams in the bracket to avoid early round matchups between teams from the same conference. This was the first season that the NCAA did not use an in-house poll process for I-AA ranking purposes; independent polling by The Sports Network wire service was used. The site of the title game, Marshall University Stadium, had been predetermined months earlier.
