NFL star Tyreek Hill is fighting for his job after being accused of breaking his 3-year-old son's arm and has penned a letter to the organization denying the allegations.

The Kansas City Chiefs wide receiver sent a four-page letter to the NFL via his attorney, N. Trey Pettlon.

"He [Hill] categorically denies he has ever 'punched' his son in the chest or anywhere on his body, or otherwise touched him in the chest in a mean-spirited manner or as a form of discipline," Pettlon wrote in the letter obtained by ESPN.

The letter states that there have been times when Hill has tapped his son on the chest and told him to "man up, buddy" or "don't cry, my man" while denying grabbing his son's arms as part of physical discipline and denies that his son is "terrified from him," referencing the leaked audio in which his fiancee, Crystal Espinal, secretly recorded telling him that their son was "terrified" of his father and that he told her that "Daddy did it" when she asked him who broke his arm

Following the audio leak, Hill was barred from Chief's activities including offseason workouts.
