SCABS are skaters who were not selected to skate for a specific team but are available to fill open team skater slots for a team's weekly game. This is done on a first come, first serve basis. A SCAB skater can only play in one game per week.
SCAB skaters were usually not selected to a specific team due to their inability to make team tryouts or their limited availability to skate in weekly games. However, personality conflicts, lack of skill, and being strongly disliked by fans may have also made them undesirable for teams to recruit.
Despite not being on a team, SCAB skaters can compete in league individual statistical categories if they meet the minimum games skated requirement.
