With Pittsburgh leading 27-9 late in the third quarter, Brown fielded a punt and returned it 78 yards for a touchdown. He turned around and ran the last 20 yards backward into the end zone, drawing an unsportsmanlike conduct penalty. The Steelers were also called for a block in the back, which negated the play.
Tomlin addressed the incident Tuesday, saying he had discussed it with his team:
"I not only spoke to Antonio, but I spoke to our team about it," Tomlin said. "Briefly, simply what I said is that it was not respectable."
Tomlin went on to describe Brown as a player with good character and the play as an out-of-the-ordinary misstep:
"Those of us that know Antonio and watch him work on a day to day basis, if one word describes him professionally, it's respectable."
Next up for the Steelers is a road date at the New York Giants Sunday, Nov. 4. Kickoff is set for 4:25 p.m. ET, and the game will be televised on CBS.
