Relegation

Relegation was determined by an average of the points obtained in the First Stages of the past six tournaments (three seasons). For the purposes of completing the relegation table, the 2007 and 2008 numbers of the 2008 Primera B champion (Real Cartagena) will be the same as the team that finished 16th in this relegation table.
