Substitution after official's time-out

[Matt S.]

Under FED rules, a substitute is allowed to enter after any dead ball, provided s/he properly reports, and it is before the expiration of a timeout. Inadverdant whistles, official timeouts, and other stoppages are all dead balls, and subs can enter. However, if this was a highly contested game, I would not stop the game for the player to tie the shoe, the team must call a timeout for this.
