The Rules of Flat Track Roller Derby

2.1 - Blocker

2.1.1 - Blockers are positional Skaters who form the pack. There can be four Blockers from each team, one of whom may be a Pivot Blocker. Blockers never score points.

2.1.2 - Prior to the start of a jam, Blockers line up behind the Pivots (if a Pivot is upright and on the Pivot Line), and ahead of the Jammers (see Section 3.2 - Pre-Jam Positioning).

2.1.3 - Blocker Identification: Non-Pivot Blockers do not wear helmet covers. Blockers’ helmets may be of the same color as the base color of a team’s helmet covers, but may not have any marks that might be confused with stripes or stars. (Skater numbers are permitted on helmets per Section 2.7.5.2).
