In his 12-year NFL career, Wes Welker played in all 16 games six times, and played in at least 13 in all but one.

The former New England Patriot also had his fair share of concussions – in fact, he suffered three that were officially diagnosed in a 10-month span.

Due to his injuries, Welker applied to receive disability benefit from the NFL, known as the NFL Line of Duty disability (LOD). According to disabilitydenials.com, former players who are not permanently disabled may be entitled to a short term disability benefit where a player gets a "substantial disablement arising out of NFL football activities."
