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."

Welker, now a wide receivers coach for the Miami Dolphins, was denied the LOD on Friday, and tweeted his displeasure with the league on Saturday morning.

MORE RETIRED PLAYERS JOIN NFL CONCUSSION LAWSUITS

"@NFL  I don’t have the time or patience for this," he tweeted. "Been an employee of the NFL for 18 years and still going. This is bush league stuff!"

The league argued that it could not prove whether or not Welker's surgeries were "performed as a result of injuries sustained while playing in the NFL."

The NFL requested Welker send additional medical records in order to receive the LOD.

Welker was a First Team All-Pro in 2009 and 2011, a Second Team All-Pro in 2007 and 2008, and was a five-time Pro Bowler who played for the Patriots, Dolphins, Denver Broncos, then-San Diego Chargers, and then-St. Louis Rams.

Welker joined the Dolphins coaching staff this offseason before stints with the San Francisco 49ers and Houston Texans.
