While Week 3 of the NFL season was producing more suspect calls during several games, the league and the locked out officials' union met, two people familiar with the talks told The Associated Press.

It was uncertain whether progress was made in an attempt to reach a new collective bargaining agreement, or when further negotiations would take place.

Officiating decisions during several games contributed to a chaotic third Sunday of the season.

The day ended with Patriots coach Bill Belichick grabbing the arm of an official following a close -- but good -- winning field goal by the Ravens as time expired. The NFL warned teams last week that it won't tolerate confrontational behavior toward the new officials.

In his postgame news conference, Belichick said he does not believe he will be fined for grabbing the official after the game.

Patriots linebacker Brandon Spikes took to Twitter to express his anger with the replacement refs.

"Can someone please tell these f------ zebras foot locker called and they're needed Back at work !!!! #BreakingPoint," Spikes tweeted.

Replacement officials admitted making two mistakes in Minnesota's victory over San Francisco, while a few other games included questionable calls that could have affected the outcomes.

Referee Ken Roan said he twice granted 49ers coach Jim Harbaugh video challenges after Harbaugh called timeout in the fourth quarter. Neither challenge should have been allowed once Harbaugh asked for time.

"What I told him was, 'Well you challenged it not knowing what the result of the play was going to be,' " Roan said. "So I granted him the challenge and we went and looked at it. That was wrong. I should not have."

Both mistakes happened in the span of six plays in Minnesota's 24-13 upset of the 49ers.

"My interpretation of it was that he could do that based upon the time factors and not knowing it was a challengeable play to begin with when he called timeout," Roan said. "If you don't have a timeout to lose, you can't make a challenge."
