It was feared Okoye would be suspended for four years if found guilty of sporting fraud.
Okoye was alleged to have been deliberately booked in Udinese’s Serie A clash with Lazio on March 11, 2024.
The 25-year-old received a yellow card for time-wasting in the 64th minute of the encounter.
Okoye will miss one Coppa Italia and seven Serie A games.
He will only be available for selection again on October 19.
