The second tier of Argentine football
32 teams divided into two divisions based on geographic location (Zones)
Teams play each other twice (30 games)
3 points for a win, 1 for a draw
League is sorted by points
Winners of each Zone play each other in a one off champions playoff final with the winner being automatically promoted
Teams finishing 2nd-4th compete in a knockout play-off system with the winner being promoted
The loser of the champions playoff final final joins the regular playoff system at the semi final stage
Still with me? You've gotta love these South American league systems!
Bottom team in each Zone is relegated
Only 4 foreign players allowed
Things change entirely in the second season as an extra two teams are put into each zone but from what I can tell there is a minimum 6 relegation spots up for grabs but the promotion method to the top flight stays the same
