Persepolis was supposed to travel to Riyadh on Friday but the flight was canceled.
The team is scheduled to meet Al Nassr in the AFC Champions League 2023-24 Group E on Monday.
The Saudi Arabian side only needs a point to confirm top spot as it sits five points ahead of Iran's Persepolis.
Persepolis was left to rue dropped points after being held 1-1 by Tajikistan's Istiklol FC on Matchday Four, the draw coming after two consecutive wins.
