Controversial NFL star Michael Vick has signed an endorsement deal with Nike, RadarOnline.com has learned.

The 31-year-old quarterback made headlines in 2007 when he was linked to an illegal dog fighting ring that landed him a federal felony charge and nearly two years in prison, followed by two months of house arrest.

"We have re-signed Michael Vick as a Nike athlete," the company's spokesperson, Megan Saalfeld, told CNN.
