While FBS football is still awaiting a playoff system, the FCS has already perfected its own, and the bracket for the nation's largest college football tournament will be unveiled on Sunday during the Football Championship Subdivision Selection show at 1:30 p.m. ET on ESPNU.

The tournament is set up similarly to the NCAA tournament in college basketball. The bracket consists of 20 teams, with 10 receiving automatic bids through conference championships. The other 10 are at-large teams chosen by a selection committee. After first-round games determine the opponents for the top four seeds, a 16-team, four-round tournament begins.

Nobowls.com predicts the top four seeds as North Dakota State, Montana State, Old Dominion and Eastern Washington. North Dakota State is 10-1 and won the Missouri Valley Football Conference. Montana State went 10-1, but their lone loss was to Eastern Washington in the Big Sky championship game. Eastern Washington is 9-2. Old Dominion finished 10-1.
