Wes Welker Molly Kentucky Derby Wes Welker has been a staple at the Kentucky Derby for a few years now. Here's Tom Brady and Welker at Churchill Downs in 2012.

 

According to an @ProFootballTalk source, Broncos wide receiver Wes Welker took the drug Molly at this year's Kentucky Derby.

 

The drug was apparently laced with amphetamines, which is a banned NFL substance, and Welker subsequently failed a league drug test. He was suspended four games by the NFL on Tuesday.
