He was found not guilty of committing lewd conduct in front of Jane Doe 5 on a separate occasion.
On Monday, Winslow was found guilty of one count of rape by force or fear, one count of indecent exposure and one count of lewd conduct, according to reports.
Wetzel said Winslow is facing 15-years to life in prison for the rape conviction.
According to the AP, Winslow faces two more rape counts involving two women.
A 77-year-old woman who went to the same gym as Winslow in the beach community of Carlsbad said he committed lewd acts in front of her, including touching himself, while Winslow was free on $2 million bail in February. The judge instructed the jurors to take as much time as they need to come to verdicts on the remaining counts.
Earlier this year, while Winslow was out on bail, he was arrested for exposing himself to Jane Doe 5 at a Carlsbad gym.
Winslow's father, Hall of Famer and former San Diego Chargers star Kellen Winslow, sat behind his son in the courtroom throughout the trial.
"Kellen Winslow took from these women what he wanted", Deputy District Attorney Dan Owens told the jury in his closing argument last week.
The former first-round draft pick and onetime highest-paid National Football League tight end was arrested on the 2003 and 2018 charges at his Encinitas, California home in June 2018.
After news of his case broke last summer, a woman called San Diego authorities to say she had been raped by Winslow at a San Diego-area house party in 2003, when she was 17 and he was 19.
That left open the likely outcome of convicting him on some charges and not others, according to three criminal defense attorneys, cited by Yahoo Sports, who aren't directly involved with the Winslow case but have followed it closely.
Winslow's attorneys, Marc Carlos and Brian Watkins, told the jury that the charged incidents were either consensual sex or never occurred at all. The charge also requires registration as a sex offender.
