DALLAS -- News 8 has learned the Dallas Police Department has determined Denver Broncos cornerback Aqib Talib shot himself in Dallas in the early morning hours of June 5.

They say his claim that he was shot by someone while standing in a park in northeast Dallas is unfounded, sources say.

Initially, Talib told police he heard a gunshot, and then fell to the ground, shot in the leg. He was driven in his Rolls Royce to a local hospital, where he was treated.

Talib refused a follow-up interview with the Dallas Police Department. Instead, his lawyer spoke for him.

Talib had also been at a strip club earlier that night where two men were shot, but sources say police could not confirm he was at the club during that shooting.

The cornerback could still face discipline from the NFL, which is also investigating the incident.
