Pittsburgh Steelers wide receiver Antonio Brown has been fined $10,000 by the NFL for taunting during last week's 27-12 win over the Washington Redskins, according to Mark Kaboly of the Tribune-Review. Brown ran backwards from the 20-yard line into the endzone when returning a punt in the third quarter. The 78-yard return was ultimately called back because of a block in the back penalty.

Since last preseason, Brown has incurred three penalties for unsportsmanlike conduct. Coach Mike Tomlin was not happy about the penalty, and told the media on Tuesday: "Briefly, simply what I said is that it was not respectable." Tomlin will now use the incident as a "learning opportunity" for the whole team.

So far this season, Antonio Brown has 40 receptions for 480 yards and one touchdown. He has also returned 15 punts for 107 yards. Brown has returned punts for the Steelers in all three of his seasons with the team.
