The incident, confirmed to Action News by the NJ Dept. of Environmental Protection, happened on the lower end of Island Beach State Park near Barnegat Inlet around 1:30 p.m.
The swimmer, a 22-year-old man, was taken to the hospital with non-life-threatening injuries.
Island Beach State Park is directly below from where the stingrays were spotted on Wednesday.
In that incident, swimmers scrambled for shore after a group of stingrays were sighted.
People initially thought sharks were swimming off the Grand and Blaine avenue beaches in Seaside Heights.
Sgt. Steven Vanhise of the Seaside Park Beach Patrol told the Asbury Park Press lifeguards launched a boat and personal watercraft and saw the stingrays, about 8-to-10 feet in size, about 200 to 300 feet off shore.
