Kellen Winslow will have to wait to learn his punishment in his rape case ... TMZ Sports has confirmed his sentencing hearing Wednesday has been postponed indefinitely over coronavirus.
The former NFL star was convicted this past year of multiple sex crimes against several women -- including the rape of a 17-year-old unconcious woman back in 2003.
At one point in the case, Kellen was staring down LIFE IN PRISON over the charges ... but he cut a plea deal back in November to ensure he'd only be facing between 12-18 years behind bars as punishment.
