Under current rules, those who exit the field of play of their own accord are not allowed to re-enter.

Mario Balotelli recently claimed he would walk off the pitch next time he is racially abused but was warned by Italian Referee's Association (AIA) president Marcello Nicchi that he would be sent off if he were to do so.
“It is not right that a player, in order to assert a right to defend themselves, must leave the field for good,” he told reporters.
“If he was forced to leave the pitch [because of racial abuse] he should not be sent off.
“Racism is a problem that needs to be solved.
“Rizzoli did well at Euro 2012. It is not a surprise choice for me.”
