INSIDER contacted Feely for comment but did not immediately receive a response.
On Saturday, Feely posted an image of himself, alongside two smiling teens in formal attire. The single-action pistol was not cocked and Feely's finger was not in the trigger well.
Shannon Watts, who founded Moms Demand Action for Gun Sense in America, wasn't laughing. Maybe this would have been more hysterical if teenagers weren't being shot to death on a regular basis all over our nation.
On Sunday, however, Feely, a father of four, wrote: "The prom picture I posted was obviously meant to be a joke". On Sunday he said the picture was 'intended to be a joke.' He added that his daughter and her boyfriend knew he was joking.
In his original post, Feely referenced a scene from "Bad Boys 2", in which Martin Lawrence's character intimidates a guy who comes over to take his daughter out on a date. "I take gun safety seriously", wrote Feely, who had a 14-year National Football League career with teams including the Chicago Bears.
