Police officers handcuffed Tyreek Hill, a wide receiver for the Miami Dolphins, outside the team’s stadium on Sunday because he was not “immediately cooperative” during a traffic stop, the president of a local police union said on Monday.

Exactly how the traffic stop unfolded remained unclear. On Monday evening, the Miami-Dade Police Department released police body-camera footage of the incident, and The New York Times was reviewing the video.

Steadman Stahl, the president of the South Florida Police Benevolent Association, said that Mr. Hill was not arrested but “briefly detained for officer safety after driving in a manner in which he was putting himself and others in great risk of danger.”

“Upon being stopped, Mr. Hill was not immediately cooperative with the officers on the scene who, pursuant to policy and for their immediate safety, placed Mr. Hill in handcuffs,” Mr. Stahl said. “Mr. Hill, still uncooperative, refused to sit on the ground and was therefore redirected to the ground. Once the situation was sorted out within a few minutes, Mr. Hill was issued two traffic citations and was free to leave.”

Mr. Hill, a 30-year-old star player for the Dolphins, was pulled over about one block from the stadium in Miami Gardens, Fla. Videos captured by passers-by and posted on social media showed him being placed on the ground by officers and handcuffed. One video showed a male officer telling Mr. Hill to put down the window of his car, and then almost immediately ordering him out of the car.

Mr. Hill later played in Sunday’s season opener against the Jacksonville Jaguars and scored a touchdown.
