State police say Branch was arrested at about 2 a.m. Saturday in the town of Cheektowaga after officers noticed Branch vomiting out the driver's side door of his vehicle.
Police say Branch failed a field sobriety test and had a blood-alcohol content of .14 percent. The legal limit is .08 percent. He was charged with driving while intoxicated and released. He's due back in court on Aug. 29. It wasn't clear if he had a lawyer.
Branch did not play in Saturday's preseason game against the Buccaneers.
In June, Bills defensive lineman Marcell Dareus was charged with drag racing and reckless endangerment after police say the 24-year-old crashed his Jaguar into a tree.
