Based on when this was tweeted...it sounds like Nikishin still had to get FROM Istanbul (if that is where he still is) TO Jeddah, Saudi Arabia. There are several flights from IST to JED (I counted 11. 8 of which have landed already) but only 1 flight from JED to JFK.
That flight departs at 3am Friday morning (5 hours from now) and lands in New York at 9am EST, which if he is on that flight, puts him in the country in time for a Friday night (in Milwaukee) or Saturday night game with the Wolves in Chicago.
