FILE - In this Dec. 6, 2015, file photo, Pittsburgh Steelers wide receiver Antonio Brown (84) leaps onto the goal post after scoring a touchdown during the second half of an NFL football game against the Indianapolis Colts in Pittsburgh. Don't twerk. Don't pretend to shoot a bow-and-arrow. Don't even think about playing basketball with a football. And, never take your helmet off.
"Hugs are always legal," Dean Blandino, the NFL's senior vice president for officiating, said in an explanatory video earlier this month.
