One attacker opted not to take it “Outside” on Wednesday, fighting and ultimately stabbing rapper Blueface in a brutal gym beatdown.

During his workout at the Kaminsky Boxing Gym in Los Angeles, California, the controversial musician faced off with an assailant armed with a knife and a rottweiler.

“I’m gonna kill you,” the attacker reportedly screamed, according to the “Thotiana” artist’s trainer, David Kaminsky. Though at one point, Kaminsky attempted to intervene, the attacker was undeterred, beating Blueface and stabbing him in the leg.

The assailant’s identity is still unknown, though a representative for the Los Angeles Police Department said he was seen fleeing the scene in a Tesla Model S with no license plates.

Blueface said the incident will ultimately sideline him from an upcoming boxing match.

“I won’t be able to fight October 14th due to a injury,” he wrote alongside footage of the attack on Instagram, noting that he “won’t have enough time to heal.”

But even with his scheduled absence, the artist-turned-fighter had one request for his fans: “Don’t say I ducked none bro came with a dog an[d] a knife at 10am,” he wrote.
