Antonio Brown calls out Smith-Schuster on Twitter

The rivalry between Antonio Brown and JuJu Smith-Schuster doesn't appear to be losing steam.

The Oakland Raiders wide receiver took to Twitter on Sunday and urged his followers to "keep your emotions off the internet." The tweet prompted a number of responses, especially from fans of his former team, the Pittsburgh Steelers.

Brown took particular exception to a response in which a fan reminded him that Smith-Schuster was named the Steelers' Most Valuable Player for the 2018 season.

The star wideout proceeded to call out his former teammate by referencing the 22-year-old's key fumble in a Week 16 loss to the New Orleans Saints. The defeat greatly hurt the Steelers' chances at a playoff berth.

Smith-Schuster was quick to fire back, referencing Brown's original tweet.

Reports surfaced in January that Brown's frustration with the team was fueled by him not being voted the MVP.

Following Brown's trade to the Raiders, Smith-Schuster tweeted a picture with "I'm Ready ... " as the caption.
