The iconic coach is to come under investigation for indecent behaviour against his Norwegian counterpart, with Rene Girard's case serving as a precedent for any ruling
The former Bayern Munich tactician was frustrated after witnessing his team squander their lead in their World Cup qualfying encounter, a match which saw several refereeing decisions go against them.
"There were a lot of emotions during the game," Hitzfeld rued to Swiss publication Blick. "I'm sorry for the gesture. I was just p****d off at not being able to take home three points.
"It's always difficult to play against twelve men [in direct reference to Spanish referee Fernandez Borbalan]."
It is still unclear whether Uefa will take a symphathetic stance towards Hitzfeld's apology for his misdemeanour however, after it meted out a ban on Montpellier coach Rene Girard for a likewise action the previous week.
Then, Girard has claimed Schalke coach Huub Stevens had provoked a response, during either side's 2-2 Champions League stalemate.
A suspension of any length would result in the 63-year-old missing Tuesday's upcoming fixture away to Iceland.
