Injured Player / Try

[bob jenkins]

From the FED 2010-2011 interps:

SITUATION 4: A1’s unsuccessful try for goal is rebounded by B1. As A1 returns to the floor after the missed try, he/she twists and then grabs the ankle and goes to the floor. B1 passes the ball to B2, who dribbles into the frontcourt and (a) attempts a try for goal which is not successful but is immediately rebounded by B4 and successfully scored; or (b) attempts a three-point try for goal which is successful. RULING: In both (a) and (b), an official stops play by sounding his/her whistle when the try for goal is released by the B player (player/team control ends on the release for a try). In (a), the successful try by B4 is not scored and play is resumed using the alternating-possession procedure. In (b), play is resumed with a throw-in to Team A anywhere along the end line. (5-8-2 Note)


How would you rule on that play in NCAA (W, if it matters)? References?
