Parker, who was married to Longoria from 2007 to 2010, said the injury has temporarily impacted his play on the basketball court, reported Us magazine.
"I was with my friend Chris Brown and me and my friends took some punches," the San Antonio Spurs player, who is part of the French Olympic basketball team competing in the London Olympics this summer, said during a press conference in Paris on Friday.
The Frenchman, who was sporting a pair of dark sunglasses during his appearance to protect his eye, was part of Brown's posse who got into a brutal fight at W.I.P. Nightclub in downtown Manhattan.
"At first it was okay, but then it started getting worse and when the plane landed it was really hurting so I went straight to the ER," Parker, 30, said about his injury.
"The cornea has been touched. I'll be missing the start of the French team, because I can't do anything for a week except keep the lens in and then take drops.
"But I was lucky. The injury won't prevent me from competing in the Olympics in any way," he added.
