The NFL offseason hasn't even started yet but Pittsburgh Steelers wide receiver Antonio Brown is already putting fans on social media watch.
CBSSports.com's Jason La Canfora reported Tuesday that Brown requested a trade from the Steelers after having a confrontation with Ben Roethlisberger and missing Pittsburgh's Week 17 win over the Cincinnati Bengals.
In what almost certainly isn't a coincidence, Brown started following the official San Francisco 49ers Instagram account.
Brown also follows 49ers players Jimmy Garoppolo, George Kittle and Adrian Colbert on Twitter.
