If rookie safety Kenny Vaccaro didn't have enough reasons to hate the Saints' Week 16 loss to Carolina, during which he fractured a fibula, he got another one on Friday.

The NFL fined him $15,750 for a horse-collar tackle on running back DeAngelo Williams three plays into the game. It was his second fine this season after he was levied $7,875 for a late hit on Falcons quarterback Matt Ryan in a Week 1 Saints win.

On the play against Carolina, Williams was sweeping left, and Vaccaro dragged him down by the collar one yard behind the line of scrimmage and near the sideline. Vaccaro leapt up to his feet, pounded his chest, stood over Williams and shouted something, earning flags for taunting and the illegal tackle.

The Panthers declined the personal foul for the horse-collar and accepted a 15-yard taunting penalty, which was enforced at Carolina's 30.

Vaccaro sustained his season-ending injury later in the first quarter. The Saints placed him on injured reserve on Wednesday.

"I definitely appreciate all the well wishes," Vaccaro said on his Twitter after his injury prompted an outpouring of support on social media. "Sure wasn't the way I wanted to end my rookie season but I'm thankful for all the support!"

Meanwhile, elsewhere, 49ers linebacker Ahmad Brooks won his appeal of the $15,750 fine he was given for a hit on Brees in the Saints' 23-20 win over San Francisco on Nov. 17, Comcast SportsNet Bay Area reported on Friday.

Officials whistled Brooks for a blow to Brees' head, negating a sack-fumble recovery for the 49ers, who were leading 20-17 with a little more than three minutes left in the game. The Saints would keep possession and subsequently hit two field goals to triumph.
