Huge news out of Pittsburgh ... where a man claims he was assaulted over the weekend by NFL superstar Aaron Donald.
The accuser is DeVincent Spriggs, who claims the L.A. Rams defensive tackle struck him in the face in the early morning hours of April 11, according to Spriggs' attorney Todd Hollis.
Hollis released a photo of Spriggs' alleged injuries -- which shows a badly damaged right eye. We're told the attorney is currently en route to a police station to file a report against Donald.
