He said that he will definitely wear a helmet if he ever rides a motorcycle again, the Pittsburgh Gazette reported.
"I recognize that I have a responsibility to safeguard my health in the off-season so I can continue to lead our team effectively," Roethlisberger said. "I never meant any harm to others nor to break any laws. I was confident in my ability to ride a motorcycle and simply believed such an accident would not happen to me."
Roethlisberger spent seven hours in surgery at Mercy Hospital after he hit the side of a car Monday. He was released from the hospital late Wednesday.
He was believed to be recuperating at his home with family members.
In his statement, Roethlisberger said he plans to be at training camp and fully able to play when the new season starts.
