New England Patriots coach Bill Belichick awoke with a fright Monday morning following a disturbance at his personal home in the American Northeast. Belichick was reportedly assaulted in his sleep by a spectral being who savagely attacked the National Football League coach, tearing his forearms from his body, extending up past the elbows.

News outlets confirm the source of the attack was, in fact, the combined cosmic energy of Belichick’s discarded or worn-out Patriots sweaters, the lot of whom joined their phantasmic energies into one sentient miasma that wrought vengeance upon the beloved coach around the stroke of midnight.

“Those close to Belichick understand his penchant for ripping the arms off of his football sweaters. He claims they restrict motion and don’t allow him to show off his Super Bowl-winning forearms,” said New England Patriots owner Robert Kraft

“I don’t think Bill ever thought it would come back to spite him so badly.”

According to a shaken and bloodied Belichick, the conjoined apparitions took the form of hundreds of different Patriots crew necks, hoodies, and sweaters, none of which had fabric lower than the bicep.

“It was a terrifying experience,” sobbed Belichick’s wife Susan, who was present at the time of the demonic visitation.

“I suppose if there is a silver lining to all of this, it’s that at least Bill can continue to wear those pullovers he loves so much.”
