Ex-NFL Player Dimitri Patterson Tackled Cop, Police Report Says

ESPN ain't sweatin' the $50 million defamation lawsuit filed by ex-NFL player Dimitri Patterson ... because the police report obtained by TMZ Sports essentially confirms their story about Patterson's insane courtroom arrest.

Patterson sued ESPN claiming the network's 2017 story about a "courtroom escape attempt" was false and defamatory ... and he wants them to pay up BIG to make things right.

But, the problem for Patterson ... the Miami Police Dept. report detailing the incident in question describes exactly what ESPN reported ... Patterson violently tried to escape a courtroom.

"The defendant ran towards the door of the courtroom to exit. While running towards the door, the defendant tackled officer B. Robert causing her to fall backwards and sustaining an injury to the back of her head."

The police report says Patterson continued to struggle with officers and pulled another cop to avoid being handcuffed. He was eventually arrested and booked for battery on an officer and resisting arrest -- both felonies. TMZ Sports has obtained his mugshot.
