As in years past, first, the league is offering a special T-shirt and scarf design by artist Maria Lauren Lambiris. You can order them on MLSstore.com or buy them in select in-stadium retailers. Proceeds benefit Children's Oncology Group.

Game-worn memorabilia will also be auctioned off via MLS WORKS starting Sept. 22.

The #ScarvesUp effort on social media is also back. For every post you hashtag #ScarvesUp on Twitter and Instagram, holding up either your Kick Childhood Cancer scarf or your favorite club scarf, MLS WORKS will make a donation to Children's Oncology Group.

Finally, you can also make a donation directly through the league’s crowdfunding page.
