SOUTHBOROUGH, Mass. (AP) - A 71-year-old Massachusetts man is recovering from a stroke he suffered while driving on a major highway and a doctor says he has his 12-year-old grandson to thank.

Benjamin Bubis, a seventh-grader from Canton, was on his way to soccer practice on Tuesday on Interstate 495 when his grandfather, Boris Hutorin, suddenly stopped talking. Benjamin says he knew something was wrong, so he grabbed the steering wheel to avoid crashing and guided the car to the side of the highway while simultaneously calling 911.

An ambulance arrived to take Hutorin to UMass Memorial Medical Center in Worcester where he was treated by Dr. Ajit Puri. Puri says Hutorin can move the right side of his body and his speech is almost back to normal. Puri says Benjamin is "absolutely a hero."
