The Ice Bucket Challenge for ALS is sweeping the country, and several of the Seattle Seahawks have participated. We have a collection of some of the challenge videos here.

Amyotrophic lateral sclerosis (ALS), often referred to as Lou Gehrig's disease, is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. It has no cure, and it is a fatal condition.

People all over the country, including celebrities and athletes, are taking part in this challenge to raise awarness and money for ALS research.

Several of the Seattle Seahawks have made videos of their participation in the challenge, freezing for the cause.
