The initial fear was that the Dutch star sustained major damage to his left eye, with his vision possibly impacted. Fenerbahce team doctor Burak Kunduraciogl allayed those fears.
"He received a blow to the eye and suffered a torn eyelid and bleeding," Kunduraciogl said. "After the investigations, we learned that nothing important happened. His condition is good."
The man himself posted the following update on his Twitter feed:
Van Persie enjoyed a strong debut season in Istanbul after moving from Manchester United. He scored 16 goals in 31 league appearances as Fenerbahce finished runners-up for the second year in a row.
The Turkish giants have struggled, however, in 2016-17. They're fifth in the Super Lig table through 10 matches, six points behind second-place Besiktas and eight points off leaders Istanbul Basaksehir.
Van Persie is tied with Emmanuel Emenike for the club lead in goals with three. Taking the 33-year-old out of the lineup would be a big blow for Fenerbahce, especially with the final two Europa League group-stage matches ahead over the next month.
Fenerbahce also face off with Galatasaray on Nov. 20, so the club will need Van Persie to make a speedy recovery if he's going to be fit for the Istanbul derby.
