"an indirect free kick is also awarded to the opposing team if, in the opinion of the referee, a player:
commits any other offence, not previously mentioned in law 12 or which play is stopped to caution or send off a player"
"Or send off a player" says it all......IFK
The off field offences I referred to were where players accidentally slide off of, or are off of the FOP and maybe one of them commits misconduct against anyone at all......drop ball at the place the ball was etc, deliberately leaving to commit an offence is an offence itself, restarting with an IFK from where the ball was when you stopped play, the special circumstances for offences committed with the ball in his own goal area taken into account for both
If a player commits an act of violent conduct on anyone other than an opponent, whilst on the field of play, and with the ball in play, he gets a red card and I restart with an IFK from the place of the offence (again clause for defender's own goal area applies)
