Section XI Rules

B Level Program - Five Period Format
The five period format is mandated for all B level teams in boys lacrosse except for those teams which have opted to be scheduled in regulation contest devices. The extra quarter format for extra participation is not an option for the B level program in Section XI.

Following are the conditions of this program:

1. Only B level teams may participate.

2. Teams shall be divided into two squads of equal numbers and UNEQUAL ability.

3. Coaches must exchange rosters prior to every contest.

4. One squad will play the first and third periods and the other squad will play the second and fourth periods. All players are eligible for the fifth period.

5. All points scored count.

6. Teams having the minimum number of 26 players are obligated to play five periods (unless on austerity) provided their opponents also meet the minimum number requirements.

7. If teams have fewer than 26 players but still can field two full teams, those teams may opt to play five periods. (If substitutes are used, note #8.)

8. No player may play in more than three periods of a five period contest.

9. There is no half-time when five periods are played.

10. Mercy rule: The clock will go to running time in the beginning of the fourth period if one of the teams is ahead by 10 goals or more. The clock will stop on all whistles when the differential goes below 10 goals.

11. Extra compensation forms presented by the officials must be signed by the home coach.

12. Each coach is requested to make a notation on the rating card verifying the extra compensation for the officials.

13. All lacrosse teams must utilize the A/B format. If there are not sufficient numbers to play 5 periods, teams will still use the A/B format but may play 4 periods.
