Warning: Video contains coarse language
Antonio Brown has already been ruled out of the Pittsburgh Steelers' Christmas Day game, but he's doing everything in his power to return from a calf injury as soon as possible.
Brown posted a video on Instagram which features the wide receiver powering through a leg workout while shouting obscenities at himself.
Reports surfaced Sunday that Brown isn't expected to be ready for a wild-card game should the Steelers have to play the first weekend of the playoffs, but as the league's leading receiver said, he's doing his best to get back.
