Marcus Peters was a sore winner.

The heat between the Rams and Saints did not end when Greg Zuerlein kicked a 57-yard field goal in overtime to lift Los Angeles to a 26-23 comeback win in Sunday’s NFC Championship in New Orleans.

Peters, the Rams cornerback who had tangled verbally with Saints coach Sean Payton in the week leading up to the game and earlier this season, ran across the field to confront Payton after the game, apparently talking trash, leading to a scrum of players from both teams.

It was a boil-over moment from the first time these teams tangled, when Saints receiver Michael Thomas beat Peters for a 72-yard touchdown late in the fourth quarter.

Afterward, Payton tweaked Peters, saying, “They were going to travel Marcus to [Thomas], and that was fine by us. We thought we liked that matchup — a lot.”

A few days later, a peeved Peters said, “Tell him to keep talking that s–t, and I hope you see me soon. We’re going to have a nice little bowl of gumbo together.”

This past week, Peters downplayed the friction, saying: “I see you all trying to make it something that it’s not. All respect to Sean Payton and what he does. I just love the fact that he’s a competitor.”

Emotions ran high in the closing moments of Sunday’s game after a controversial no-call on a possible pass interference let the Rams have a chance that they took to a Super Bowl berth.
