Marvin Norwood, 30, and Louie Sanchez, 31, faced charges of mayhem, assault and battery in the beating of Bryan Stow, 44, after a baseball game at the stadium.
Stow, a Northern California resident, suffered head trauma and a permanent disability, indicating he will require care for the rest of his life.
Norwood received a four-year sentence in Los Angeles Superior Court after he pleaded guilty to assault causing great bodily injury. Sanchez pleaded guilty to one count of mayhem and received an eight-year sentence, the Los Angeles Times reported.
Stow was attacked after he and three friends, each a San Francisco Giants fan, walked through a parking lot after the Dodgers' 2011 Opening Day win over the Giants. Witnesses at a preliminary hearing in 2013 described drunken and profane behavior by Sanchez against the group.
