PITTSBURGH (AP) — Pittsburgh Steelers wide receiver Antonio Brown has apologized for livestreaming video from the team's locker room following its win over Kansas City.

Brown posted a message late Tuesday on Facebook and Twitter saying that he let his "emotions and general excitement get the best of" him. Brown's 17-minute long livestream caught coach Mike Tomlin using a handful of profanities during his postgame speech, including a derogatory term for AFC championship game opponent New England.

Tomlin said Brown will be disciplined internally but will be on the field on Sunday.
