Former NFL linebacker Tim Shaw says he has ALS

NASHVILLE, Tenn. (AP) — Former NFL linebacker Tim Shaw has announced that he has ALS.

In a video posted Tuesday on the Tennessee Titans' web site, the 30-year-old Shaw reveals he was recently diagnosed and says "I'm here today to stand up and fight with all of you against this disease" before pouring a bucket of ice water on his head as part of the Ice Bucket Challenge to raise money and awareness to battle ALS.

He then challenges the Titans organization, Penn State's football team and "my Clarenceville community" to do the same. Shaw played at Penn State and Clarenceville High School in Livonia, Michigan.

Shaw played for the Carolina Panthers (2007), Jacksonville Jaguars (2008), Chicago Bears (2009) and Titans (2010-12). He announced his retirement from football earlier this year.
