Following up on their first support initiative the week of the Japan Earthquake and Pacific Tsunami, EA will be donating all of the proceeds from FIFA Ultimate Team pack sales for tomorrow only. The FUT packs are virtual "packs" of trading cards that translate to players you can manage and add to your team. You can also trade items and actions with other players, much like actual trading cards. EA hopes to utilize the international passion for Football (re: Soccer for all you Americans) to promote and provide further aid to Japan after the series of tragic events that befell the country last less than two weeks ago:

We know that football is a unifying force around the world, and we hope that our fans will join us in harnessing this positive force to help raise money for those that need help.

The promotion begins at 00:01 GMT Saturday March 26 and will continue for the following 24 hours. You can see the original post and learn more about how to give back with FUT on EA's blog.
