What happens when a football player needs to use the toilet when in the middle of a professional match?

Played a 5 aside football match with with my friends today and in the middle of the match I felt the need to use the toilet, so I just beckoned on someone to replace me while I zoomed off.

Now what if I was playing professionally in a match aired on television, What would I have done?
Google is giving me conflicting answers

he is free to excuse himself, he can signal the ref or better still tell his coach..
if he isnt dt needed in d game, he would be subbed but if he is important, the team would play with a man down till he is done...
he is allowed to obey the call of nature but the match wont wait for him...I remember a game drogba was running to use d toilet after halftime, auba did same last season I think n even a totenham player did so quickly after asking to be subbed..

It's not really common

But I guess they can treat the case as emergency response...

If he doesn't take long and your team can manage with 10men...he can rejoin the match
