What Is 2017 Primera B de Chile

Overview

The 2017 Primera B de Chile served as the second-highest division in the Chilean football league system, operating beneath the top-tier Campeonato Nacional. This season marked a structural shift, transitioning from the traditional Apertura and Clausura split format to a single-season competition, aligning more closely with international standards.

The league featured 14 teams competing in a round-robin format, with each club playing 26 matches. The season began on February 11, 2017, and concluded on December 13, 2017, culminating in a final between the top two teams to determine the champion and promotion candidate.

• Coquimbo Unido emerged as champions after defeating C.D. Cobreloa in a two-leg final, winning 3–1 on aggregate.
• The league abandoned the Apertura and Clausura system for the first time, adopting a unified season to streamline promotion.
• Each team played 26 matches, facing every opponent twice—once at home and once away.
• Deportes Antofagasta and San Marcos de Arica were relegated at the end of the 2016 season, replaced by new entrants.
• The champion earned direct promotion to the 2018 Primera División, while the second-placed team entered a playoff for the second promotion spot.

How the 2017 Primera B Season Worked

The 2017 season introduced a new competition model designed to improve clarity and excitement, replacing the fragmented Apertura and Clausura with a single-table format. This change allowed for a more consistent evaluation of team performance across the entire calendar year.

• Single-Table Format: All 14 teams played 26 matches, with the top two advancing to a two-legged final for the title and promotion.
• Finals Structure: The first-place team hosted the second leg, giving them a slight advantage based on regular-season performance.
• Promotion Rules: The champion earned automatic promotion to the Primera División, while the runner-up entered a playoff against a bottom-tier top-flight team.
• Relegation: The bottom two teams in the standings were relegated to the Tercera División, increasing competitive stakes throughout the season.
• Scoring System: Teams earned 3 points for a win, 1 for a draw, and 0 for a loss, with tiebreakers based on head-to-head records.
• Player Eligibility: Foreign players were allowed, but clubs could only register four non-Chilean nationals per squad, per league regulations.
