Pittsburgh Steelers wide receiver Antonio Brown appeared to fire a thinly veiled shot at New York Giants defensive end Jason Pierre-Paul on Monday when asking everyone to be safe on Independence Day.
Pierre-Paul famously lost part of his right hand in a fireworks accident during last year's Fourth of July celebrations.
The 27-year-old starred in a new public service announcement for the U.S. Consumer Product Safety Commission, giving a warning about the dangers of fireworks.
