Brady was reportedly "shaken" by the crash -- but a source has told ESPN that he did not go the hospital. Brady is now en route to Gillette Stadium -- home of the Pats.
Law enforcement sources tell TMZ ... one passenger in the other car is at the hospital and being treated for "serious injuries." We're told the driver of the other car was "fine."
A law enforcement source tells TMZ ... based on the preliminary investigation ... it appears Tom Brady was not at fault -- that he had the green light.
Thanks to My FOX Boston for the pictures.
UPDATE: The driver of the other car was ticketed for running a red light.
