CBS Sports columnist Charley Casserly reported that the two men had a hair battle spectacular before Moss was recently traded to the Minnesota Vikings.
According to Casserly's account, the men verbally tussled (or should we say tousled?) in the Pats locker room after Brady chided Moss for his recent lackluster play and told him to lose his facial hair.
Moss allegedly responded that Brady needed to cut his long hair because he looks "like a girl."
No argument there from the Boston media, which has been pleading with Brady for months to return to his clean-cut locks of seasons past.
Even the oft-imitated originator of Brady's side-swept bangs, teen heartthrob Bieber, recently joined Hub pundits in mocking the 32-year-old football star for his youthful tresses..
Bieber told the Boston Herald, "Nice hair, Brady. Dude's got some golden locks. Ha ha!" in response to questions about the quarterback's mop top.
Meanwhile, Patriots coach Bill Belichick has reportedly said that the feud was "news to me" and claimed no knowledge of the hair fight.
