Detect when player is dropped from the server

When a player connects to the server, sometimes for whatever reason they’ll be dropped from it before they can actually enter the game. This is evident because when it happens, the message “Dropped player xyz from server” appears in the console. Is there a hook I can use to tell when this happens?

Have you tried http://wiki.garrysmod.com/page/Game_Events ?

Thanks, the player_disconnect game event seems to encompass players dropped while connecting.
