NASHVILLE, Tenn. -- A couple members of the Tennessee Titans have done the Ice Bucket Challenge to help raise funds and awareness for ALS.

But there has not been large-scale participation, and Tuesday evening we learned the reason: The team has been waiting for an announcement from former Titans linebacker and special-teamer Tim Shaw that he has been diagnosed with the disease, and players are expected to answer his challenge soon, collectively.

Shaw revealed his diagnosis in a short video posted on the team’s website, then challenged the Titans, the Penn State football team and the community where he went to high school, Clarenceville (Mich.).

Shaw was a popular role player in Tennessee after the Titans added him and Patrick Bailey before the 2010 season in hopes of bolstering their special teams.

Shaw is a proud Penn State alumnus who willingly discussed Joe Paterno, Jerry Sandusky and the sexual abuse scandal that unfolded on campus and landed Sandusky in jail.

His diagnosis is terrible news, but he has quickly put himself in position to help the cause. The Ice Bucket Challenge is raising awareness of the disease and helping to raise funds to research a cure.
