The Jets let their frustration show after Rodgers hit Randall Cobb with a 2-point conversion pass that gave the Packers their first lead, 24-21, with 5:45 to play in the third quarter.
It erased an 18-point Jets lead and led to a brief skirmish that saw Jets defensive lineman Muhammad Wilkerson, a second-team All-Pro last season, get ejected for throwing punches.
"It's just football. It happens," Lang said. "Randall caught the ball and they blew the whistle and (the referee) had the signal that it was good, and the guy was trying to tackle him after the whistle was blown and Josh (Sitton) and I went over and tried to get him off. After that, everybody just kind of started shoving each other. I didn't see any punches thrown, but obviously the refs caught something to merit an ejection. But that type of stuff happens.
"Losing that kind of lead I imagine is pretty frustrating. I don't know if that had anything to do with it. It really wasn't a chippy game up until then. But stuff happens. They're trying to make a play, we're trying to defend our guy. People are going to get shoved once in awhile."
The Packers' sideline was called for unsportsmanlike conduct after a Jordy Nelson catch to the Jets' 28 with the Packers trailing 21-3 in the second quarter.
"That's disappointing," McCarthy said. "(Line judge) Byron (Boston) called it on our bench. He said someone said some things to him, and he reacted quickly. Obviously at the end of the play, I don't remember who exactly was going out of bounds, but there looked to be a potential late hit. Things were said and a flag went up. I've talked to a number of people, I talked to Byron about it a couple times. I don't know who he threw it on. That's what's kind of in question. But the penalty was on our bench, which is not — we're not going to do that no more."
