Clipper Darrell is famous for being the Los Angeles Clippers' biggest fan, and now he's even more famous after getting knocked out on video.

As TMZ reports, the superfan, who's real name is Darrell Bailey, got into an altercation with a security guard when the Clippers faced the Boston Celtics on Monday, December 12 at Crypto.com Arena.

Basically, the security was trying to stop Bailey from walking somewhere, Bailey still tried to get past him, so the guard put his arm around his neck.  And that's when the guard decked the super fan, knocking him out cold.

"After receiving immediate medical attention, Darrell was transported to a nearby hospital for further evaluation and treatment," said the arena's President Lee Zeidman. "An investigation of the incident was launched which determined the employee’s behavior to be a direct violation of our training and approved responses resulting in the immediate termination and arrest of the employee by the LAPD."

In regards to Bailey's current condition, he told TMZ that he's still suffering from headaches and is taking medicine.
