Some Texans players will be sporting a different look Sunday against Green Bay -- but it’s all for a good cause.

"My Cause, My Cleats" is an NFL campaign that allows players to showcase their causes with custom cleats during Week 13.

More than 500 players will participate.

“One of the great NFL traditions is how our players passionately support important causes in their communities and around the globe every year,” said NFL Commissioner Roger Goodell. “They are incredibly creative by nature so we are not surprised how they are seizing the opportunity this week with inspiring expressions of their charitable commitments on their cleats, online and through social media.”

Players can raise funds for their cause by auctioning their cleats at NFL Auction.
