BOSTON — (CNN) We’ve moved on from “Deflategate” to “Headsetgate.”

Thursday was supposed to be a night of celebration for the Super Bowl champions, but the New England Patriots have found themselves at the center of yet another controversy.

In very terse language, Pittsburgh Steelers head coach Mike Tomlin said that he and other Steelers coaches heard the Patriots’ radio broadcast “for the majority of the first half” on their headsets, impeding their ability to communicate with each other. The Steelers lost to the Patriots 28-21 in Foxborough, Massachusetts, in the National Football League’s regular-season opener.

Tomlin said headset issues happen all the time when his team plays at Gillette Stadium, the Patriots’ home field.

“That’s always the case,” said Tomlin, who is in his ninth season as Pittsburgh’s head coach. “Yes. I said what I said.”

Asked if he got a satisfactory resolution, Tomlin answered, “Eventually.”

A game story on the Steelers website didn’t mince words, calling it “no surprise at all” that it happened.

“This is the kind of stuff that happens to the visiting team in Gillette Stadium all the time,” Bob Labriola wrote. “From the start of the game through the opening 14 minutes of the first quarter, the Steelers’ coaches’ headsets were receiving the Patriots Radio Network broadcast of the game. The broadcast was so loud that the Steelers coaches were unable to communicate, and the NFL rule is that if one team’s headsets are not working the other team is supposed to be forced to take their headsets off. It’s what the NFL calls the Equity Rule. Strangely enough, whenever an NFL representative proceeded to the New England sideline to shut down their headsets, the Steelers’ headsets cleared. Then as the representative walked away from the New England sideline, the Steelers’ headsets again started to receive the Patriots game broadcast.”

In a statement released Thursday night, NFL spokesperson Michael Signora said that the coaches’ communications equipment was provided by the league.

“In the first quarter of tonight’s game, the Pittsburgh coaches experienced interference in their headsets caused by a stadium power infrastructure issue, which was exacerbated by the inclement weather,” Signora said. “The coaches’ communications equipment, including the headsets, is provided by the NFL for both clubs use on game day. Once the power issue was addressed, the equipment functioned properly with no additional issues.”

After the game, head coach Bill Belichick said the Patriots also experienced headset problems during the game.

“We had a lot of problems,” Belichick said. “We had to switch headphones a couple times. The communication system wasn’t very good. We deal with that, it seems like weekly. Yeah, they told us they were on the verge of shutting it off, but then they I guess they got it working. I don’t know, but it was a problem the whole game. We almost had to switch helmets with Brady there at the end — couldn’t get the plays into him. It was a problem all night.”

Belichick said he did not get an answer to what the problem was, adding that technology is “not really a very strong area for me.”

In the Steelers’ locker room after the game, linebacker Ryan Shazier didn’t blame the headsets for the game’s outcome. “I think we just have to do a better job,” he said.
