Tank Dell, 24, who suffered a "minor wound," was treated at a hospital and released, the Texans said Sunday.
The team said the violence took place in Sanford, about 40 miles south of Dell's hometown, Daytona Beach.
Seminole city police spokesperson Bianca Gillett said no shootings were reported there overnight.
A 16-year-old boy was arrested in connection with the attack, the sheriff's office said.
A security guard working at the venue quickly apprehended a suspect, the office said, and turned him over to two deputies who rushed to the scene.
The venue said the violence took place during a private event. In a statement, it called the attack an "isolated incident."
"We are cooperating with the Seminole County Sheriff’s Office and praying for all those involved," it said.
