Minnesota Vikings punter Chris Kluwe and offensive lineman Matt Kalil have entered into a friendly bet for the upcoming game between UCLA and USC, as the Vikings have a bye this week.

Both players will be attending the game and Kluwe took to Twitter, like he often does, to announce the rules of the bet. After the game, the loser has to do pushups equal to the winning team's score at the midfield.

Made a bet with @mattkalil today on U$C/UCLA game. Loser has to do pushups equal to the winning team's score, at midfield after the game.

Kluwe attended UCLA from 2001-2004 and placed first in the NCAA for number of punts and total yards in 2003. Kalil was a member of the USC Trojans from 2008-2011, although he redshirted in 2008. He was a semifinalist for the 2011 Lombardi Award.

The USC and UCLA game doesn't just have ramifications for the arm strength of Kalil and Kluwe. USC currently sits in second place in the Pac-12 South at 5-3, with one more loss than the 5-2 UCLA Bruins.
