FOXBOROUGH, Mass. — Patriots cornerback Alfonzo Dennard was arrested and accused of drunken driving Thursday in Nebraska while on probation for assaulting a police officer, the second New England player to get in serious legal trouble this summer.

Dennard’s early-morning arrest in Lincoln, Neb., where he was a college star for the Cornhuskers, came 15 days after Aaron Hernandez was charged with murder and three days after Patriots owner Robert Kraft said the club will “be looking at our procedures and auditing how we do things” with regard to character reviews.
