Vikings star Adrian Peterson should be arrested anew after admitting during his court appearance on a child-abuse charge that he had "smoked a little weed" while out on bond, prosecutors said Thursday in Houston.

In a court motion, the Montgomery County District Attorney's Office said Peterson allegedly told a worker conducting his urinalysis exam during a Wednesday court appearance that he had smoked marijuana. Bond terms typically include not taking any illegal drugs.

"In light of this statement, and the fact that it was made during the urinalysis testing process, and the term 'weed' is a common slang term for marijuana, the state argues that the defendant has smoked marijuana while on bond," the district attorney's office wrote.

Peterson is free on a $15,000 bond after he was indicted last month on a felony charge of injury to a child for using a wooden switch to discipline his 4-year-old son earlier this year in suburban Houston. Peterson has said he never intended to harm his son and was only disciplining him in the same way he had been as a child growing up in East Texas. He faces up to two years in prison and a $10,000 fine if convicted.

Peterson is on paid leave from the Vikings under a special exemption from the NFL commissioner until the legal case is resolved. Vikings coach Mike Zimmer said he had no comment when asked about it after practice Thursday.

Wrong headgear

San Francisco quarterback Colin Kaepernick said he has been fined $10,000 by the NFL for the pink "Beats by Dre" brand-name headphones he wore around his neck after Sunday's game.

While Kaepernick has an endorsement deal with Beats and has done a commercial, the league's contract is with Bose. Wearing the pink version for breast-cancer awareness month, Kaepernick knew he could be subject to a fine after the 22-17 win Sunday.

Yet it's more than the $8,286 fine the Broncos' Julius Thomas faces for a chop block on Cardinals defensive end Calais Campbell.

Penalties way up

NFL games are averaging about 17 penalties, up more than two per game from 14.7 at this point in 2013, according to the league, and the man in charge of officiating is OK with the trends, in part because games are actually running a few minutes shorter.

"I'm certainly not surprised that fouls are up. . . . We're in a good place," NFL vice president of officiating Dean Blandino said in a telephone interview.

"I don't see a diminished product on the field," he said.

Illegal contact, defensive holding, defensive illegal use of hands, and offensive pass interference are all at Week 5 highs over the last 20 years, Stats said, and the jumps from 2013 are staggering, particularly for illegal contact (which has more than tripled, from 15 to 56) and defensive holding (more than doubled, from 52 to 113).

There already have been more illegal-contact calls than the 54 for all of last season.

Blandino's message: Don't expect things to go back to the way they were.

"If we pull back now, then we aren't being consistent, and I think that's important," he said.
