Case 6.4.6 Situation A:

Team A is awarded the ball for a throw-in under the alternating procedure. Team A commits a violation.
RULING: B's ball for a throw-in because of the violation. In addition, the possession arrow is reversed and is pointed towards B's basket. Team B will have the next opportunity under the alternating procedure. Team A has lost its opportunity by virtue of the violation. A team loses its turn under the procedure.
COMMENT: If a foul by either team occurs before an alternating-possession throw-in ends, the foul is penalized as required and play continues as it normally would, but the possession arrow is not reversed. The same team will still have the arrow for the next alternating-possession throw-in. The arrow is reversed when an alternating-possession throw-in ends.
