What happened: Warner was docked for two separate violations coming out of San Francisco's win over Arizona last week. One fine covered a hip-drop tackle, and the other stemmed from improper use of the helmet.

Why it matters: The penalties add league discipline to a 49ers week already under scrutiny and put added focus on how Warner finishes tackles going forward. They also follow recent attention on Fred Warner's play as San Francisco tries to build on a 3-0 start.

What to watch: Any appeal outcome would determine whether the amount changes. Warner's next game will also show whether officials monitor his tackle technique more closely after the review.
