So, you think you know football? Here’s a chance to prove you really know your teams. Put your sports savvy to the test and win weekly prizes playing the Daily Camera’s Pro Football Challenge.

It’s free and easy to play. Just go to to sign up and play. Then enter your picks for the winners in each pro football game (playoff games, too!) and predict the score for the winning and losing team for the designated tiebreaker game each week.

You can enter your picks and score predictions any time until five minutes before the start of each game. You’ll be competing with fellow sports fans for prizes and bragging rights among friends. We’ve even included a place on the site to talk some sports trash with other Pro Football Challenge players. Complete contest rules and instructions are available on the contest site.

Good luck picking your winning teams!
