New England Patriots cornerback Stephon Gilmore took issue with Pittsburgh Steelers wide receiver Antonio Brown during Sunday’s 17-10 loss.

The two were engaged in a disagreement in the third quarter before officials stepped in to separate the players, and no penalty flags were thrown.

Gilmore, who covered Brown for most of the game, explained after the game what caused the confrontation.

Brown finished the game with 49 yards receiving and a touchdown on four catches, but the touchdown grab in the second quarter came with cornerback Jason McCourty in coverage.

Despite the short confrontation between Gilmore and Brown, Gilmore expressed no hard feelings. Instead, Gilmore showed respect in his matchup against one of the NFL’s top offensive weapons.

“It was fun,” Gilmore said. “He’s one of the best receivers today. One thing that he’s good at — it’s not his routes — but his (timing) … when he makes his move. He’s very good at it.”

Just another day at the office.
