Pat Morris tells The Associated Press in an email that Canadian prosecutors found there was not enough evidence to proceed and dropped the charges against O'Reilly of impaired driving and failing to remain at the scene. The case has been dismissed.
The London Free-Press first reported the charges being dropped.
Police said a green pickup truck was driven into the side of a Tim Hortons restaurant in Lucan, Ontario, north of London, around 4 a.m. on July 9, 2015, before driving away.
O'Reilly, 25, will be starting his second season with the Sabres after a trade from the Colorado Avalanche in the summer of 2015. Buffalo signed him to a franchise-record $52.5 million, seven-year contract after acquiring him.
