NBA legend Scottie Pippen is facing a $4 million lawsuit as a result of an altercation outside a Malibu, Calif., restaurant last month.

The lawsuit -- filed on Thursday at Los Angeles County Superior Court -- alleges that Camran Shafighi, 49, was beaten after asking Pippen for an autograph and a picture for his girlfriend’s son. "Instead of a photograph for the boy, [Shafighi] received from Pippin ... a verbal assault, a spit in the face, followed immediately by a physical beating consisting of a shove, then a violent punch to the face and head that felled Mr. Shafighi to the ground," reads the lawsuit, according to E! News.

The lawsuit also states that Shafighi did not physically provoke the fight or fight back, “as he was knocked unconscious with the first blow.”

Chicago Tribune reports that Shafighi is suffering from an array of medical issues ranging from headaches and nausea to breathing difficulties after his confrontation with the Chicago Bulls star.

"This has been pretty devastating to him," Shafighi’s attorney Lee Boyd told the Tribune. "This was not the result of some drunken barroom brawl. This is a guy who wanted to take a picture with a cellphone."

Los Angeles County Sheriff’s officials say that Pippen was having dinner with his family at the popular Nobu restaurant in Malibu when approached by Shafighi. Sheriff’s spokesman Steve Whitmore said that several witness described Shafighi as being intoxicated.

"'Sources' close to Mr. Pippen have suggested that our client used a racial slur prior to this attack,” Boyd told E! News. “This claim is simply not true."

After the fight, Shafighi was treated for a head injury at a local hospital and released the following morning. Pippen -- who is represented by famed attorney Mark Geragos -- voluntarily came into a police station to be questioned by investigators and left without being arrested.

Pippen spent nearly two decades playing in the NBA. He won six championships playing alongside Michael Jordan as a key player on the Chicago Bulls during the '90s. Pippen also won a gold medal at the 1992 Olympics as a member of the famed Dream Team. In 1996, he captured gold again at the Summer Olympics in Atlanta.
