Henry Ruggs now faces FIVE total charges in connection to his fatal car accident this week... four felonies, TMZ Sports learned.
According to court records, the ex-star of the Las Vegas Raiders has been charged with DUI resulting death, DUI resulting substantial bodily injury (presumably for the injuries sustained by his GF, the passenger) and two reckless driving offenses -- all felonies.
Ruggs was also charged Friday with misdemeanor possession of a firearm while under the influence.
Ruggs could spend up to 46 years in prison if he is convicted of all charges.
