There's a lot on the line in Sunday's Seahawks-49ers game. Including one very famous eyebrow.

During one of the new Madden commercials Russell Wilson and Colin Kaepernick make a bet. Many think this is a real bet that will take place after Sundays game.

Young quarterbacks Colin Kaepernick and Russell Wilson, channeling their inner frat guys, will be going head to head at Seattle and, apparently, the loser has to shave off one of his own eyebrows. All I know is that I hope they are serious.

These teams are bitter rivals that are gunning for the NFC West crown, and while they appear chummy on the set of this Madden NFL 25 promotional shoot, I can't forget the old saying: "Keep your friends close and your enemies closer."

The 49ers travel to Seattle for Sunday Night Football this week.

Who do think will be losing an eyebrow this weekend? Leave your prediction in the comments below!
