Short timeout

[Mark Dexter]

Situation tonight - A1 is in the corner of his frontcourt, off balance, and calls a timeout rather than falling OOB.

Team B (which had no subs) ran over to the bench to sit down. Several members from team A start saying that they just wanted a "quick" timeout, to which I explained that once a timeout is granted (in NFHS) it can only be shortened if both teams are ready to play.

The supervisor at the table then called me over and said that there was a new rule this year which allowed teams to call a short timeout for subs, with play immediately resuming. Not knowing what to think, I simply replied that team A did not have any subs ready, so there would be a full timeout.

Now, did I somehow miss this rule change, or is this guy halucinating?
