Time-out, 4 return, when can 5th return?

[Illini_Ref]

Now don't just post part of 3-1-1. Read the "Note" below the section.

tjones' point is this. You cannot discover that all eligible players didn't return to the floor until one comes in late. To do so would be guessing on who is injured, sick, has a uniform problem, blood problem, etc. If you call a technical because a kid is puking on the bench and didn't come out of a timeout, I think you are wrong. Now if he pukes, then runs in after the throw-in, whack him.
