Josh Allen's Halloween costume was driven by more than just standard golfer's attire.

Upon arriving to Highmark Stadium before Sunday's game vs. Miami, the Buffalo Bills' fun-loving quarterback embraced the entirety of golf legend Phil Mickelson's persona, from Lefty's shiny sunglasses and golf shorts – with careful emphasis on the chiseled calves – to his trademark thumbs up and tip of his visor.

Allen's costume naturally caught the intention of Mickelson, an icon of his sport and winner of six of golf's major tournaments, who was quick to chime in on Twitter.

Allen revealed in his postgame news conference that he and Mickelson had met over the summer, and that the golfer spoke to the Bills during training camp about how to regain poise during difficult circumstances.

In fact, all of the Bills' quarterbacks, including Mitch Trubisky, Jake Fromm and Davis Webb, mimicked professional golfers as they arrived to the stadium before the 1 p.m. kickoff.

Social media commenters eagerly encouraged Mickelson to return the favor to Allen and wear the quarterback's Bills jersey while on the course in the future.

Much has been made of the ageless Mickelson's fashion quirks, with full-length stories devoted to his unmistakable sunglasses, his bulging calves and his commitment to a traditional gesture. Not shockingly, one of the commonly asked questions on Google, at least in Mickelson-related searches, is "how do I get my calves to look like Phil Mickelson's?"
