Pittsburgh Steelers wide receiver Antonio Brown missing Sunday's 16-13 win over the Cincinnati Bengals reportedly resulted from an argument with a teammate rather than a knee injury.
According to Gerry Dulac and Ed Bouchette of the Pittsburgh Post-Gazette, Brown threw a football at one of his teammates in an "unspecified heated dispute" during Wednesday's walkthrough and then didn't practice for the remainder of the week.
Brown was reportedly not present for Saturday night's team meeting, and it was his decision to sit out practice.
Per Dulac and Bouchette, Brown showed up to the game Sunday and expected to play, but he was declared inactive and left at halftime.
