Jake Shields, Mike Jackson erupt in physical altercation at UFC PI over social media insults; both threaten legal action

Online bad blood spilled over into real life for two UFC veterans.
Former Strikeforce champion Jake Shields posted a video on Twitter on Friday showing a physical altercation between him and four-fight UFC veteran Mike Jackson, which took place at the UFC Performance Institute in Las Vegas. Shields and Jackson have clashed extensively on social media over a variety of issues such as race, politics and more.
“Finally ran into Mike Jackson,” Shields wrote on Twitter. “He quickly discovered the difference between calling people Nazis in person and on Twitter. This racist is lucky so many people were there to save his pathetic racist ass.”
In the video, which can be seen below, Shields is shown controlling Jackson from side control and then mount position as several bystanders stand around watching the pair. “You’re a little b****, you said you were going to screw me up,” Shields tells Jackson in the clip, prompting a response from Jackson asking the gathered crowd for help. Shields then appears to rise from the mount and punch Jackson before the clip ends.
In a follow-up tweet, Shields invited Jackson to the Xtreme Couture gym for a rematch, explaining “they dragged me away [Jackson] because he begged for mercy.”

After the incident, Jackson and Shields continued to attack each other on Twitter, with Shields repeatedly calling for Jackson to show up at Xtreme Couture and Jackson indicating that he left the former Strikeforce champion with a bloodshot eye.
I bet you are with XC and not the PI. You were banished because you couldn’t control the white fragility running through your nazi veins. You are nothing but a vile thug, Yakub. https://t.co/dIgBPqHa7L

Jackson told MMA Fighting’s Steven Marrocco on Friday afternoon that he plans to file charges against Shields for the incident.
Shields told MMA Fighting that he spoke with a lawyer who said he has solid ground for a defamation suit against Jackson for his Nazi-related accusations.
Jackson, 37, split his four UFC appearances, with wins over CM Punk (later overturned to a no-contest due to testing positive for marijuana) and Dean Barry between first-round stoppage losses to Mickey Gall and Pete Rodriguez.
Shields, 43, retired from MMA in 2018 after a first-round knockout loss to Ray Cooper III in the PFL playoffs. The veteran whipper has notable wins over Dan Henderson, Tyron Woodley, Demian Maia, Carlos Condit, Robbie Lawler, Paul Daley, and more.
