According to the Saints, Gleason was resting at Ochsner Hospital with his family. His wife, Michelle, said Gleason was responsive and believes he will be OK.
Gleason later tweeted that he was doing fine:
Gleason, 35, publicly announced last year that he has ALS, or Lou Gehrig's Disease. He's now confined to a wheelchair and has difficulty speaking.
Gleason was a special-teams standout who earned his place in Saints lore for his blocked punt on Sept. 25, 2006, in the team's return to the Superdome following Hurricane Katrina. A statue outside the stadium immortalizes the famous play.
