Canadian Modifications

• Please note: FIBA has approved the following 2-person mechanics changes on an experimental basis in Canada:

· No preferred diagonal (i.e. Trail can officiate on either the left or right side of the court)

· Trail on opposite side for all free throws (facing the scorer’s table)

• Please consider these modifications when referencing the FIBA 2-Person Mechanics Manual.

FIBA 2-PERSON MECHANICS

PRE-GAME (FIBA protocol to be applied where appropriate)

• On the court 20 minutes before game time

• Opposite the table• Make sure scoresheet is

correctly prepared and that, 10 minutes before game time, coaches confirm list, indicate five starters, and sign scoresheet

• Introduction:– 6 minutes before game time,

blow the whistle to interrupt warm-up and bring teams to respective bench (clock still running)

– After presentations are made, resume warm-up with 3 minutes on the clock

– 2:00 minutes, officials come across floor to table side

– 1:30 minute left, blow the whistle to bring teams to bench

– Pre-game and half-time: whistle at 3:00, 1:30 and 30 seconds

– Between 1st and 2nd, 3rd and 4th, and before OT, whistle at 30 seconds

• Movement of officials

• R remains stationary• U must verify that the

tap was legal, i.e. that the ball had reached it’s highest point before being tapped and that the movement of the 8 non-jumpers was according to the rules.

OPENING TOSS

• Movement of officials

• R remains stationary• U must verify that the

tap was legal, i.e. that the ball had reached it’s highest point before being tapped and that the movement of the 8 non-jumpers was according to the rules.

• Always move when the ball moves

• Box-in all players• Move to see the air
