I seem to remember past discussions on baseball forums where it was stated that other amateur codes have a similar rule. Beats me, though. Just like with softball, there are a dozen different alphabet soup organizations out there and I wouldn't hazard a guess on what they all have to say about this.
From 2009 NFHS SB Rules pdf..
5-2-d. when an umpire or player is incapacitated, unless injury occurs during a
live ball, then time shall not be called until no further advance or putout is
possible.
NOTE: If necessary, the umpire may suspend play immediately if, in the umpire’s
judgment, further play may cause injury or jeopardize a participant’s safety. (10-2-3g)
