frank gore

Frank Gore grabbed a naked woman by her hair and dragged her across a hotel room’s hallway during an altercation in Atlantic City, N.J. last month … according to new, bombshell court documents obtained by TMZ Sports.

Cops say the incident between the NFL legend and a 28-year-old woman happened in the early morning hours of July 31 on the 59th floor of the Tropicana Casino’s Havana Tower.

According to the docs, Gore "forcibly" gripped the woman by her hair … before "violently dragging her nude person along the floor of the 59th hallway."

Frank Gore Playing Through The Years

As we previously reported, Atlantic City Police said officers were initially called out to the scene at around 8:11 AM on the 31, but did not make any arrests after they said the woman "did not exhibit signs of injury."

Gore, though, was ultimately charged days later with simple assault after cops said they further investigated the allegations.

Gore, according to records, is due in court for a hearing in the case in October.

He’s yet to publicly comment on the accusations.

The former 49ers star is considered one of the greatest NFL running backs of all time — after rushing for 16,000 yards in his 16-season career. The 39-year-old has since become a boxer, winning his last fight in May over Yaya Olorunsola.
