Knight has a history of legal problems
Former Death Row records boss Marion "Suge" Knight has been treated in hospital for facial injuries after a fight in a US hotel on Monday morning.
Security guards at the W hotel in Scottsdale, Arizona, called police after two groups of guests exchanged "heated words in the VIP area".
Officers at the scene reported that Mr Knight was punched twice in the face.
The fight was broken up using taser stun guns. Two men were arrested and charged with aggravated assault.
They were named by police as Leon Anderson and Robert Carnes Jr, who identified himself as a business manager for R&B star Akon.
Akon was not present during the fracas.
Knight sustained broken facial bones and was taken to hospital, the police report said.
The rap mogul is best known for launching the solo careers of Dr. Dre Snoop Dogg on his label, Death Row Records.
He sold tens of millions of records before collapsing in debt and mismanagement in 2006.
After Knight filed for bankruptcy, the label was sold at auction for $24m (£12m).
Always a magnet for controversy, his career has been overshadowed by run-ins with the law in recent years.
Last August, he was arrested in Las Vegas on drug and assault charges after allegedly punching his girlfriend and pulling a knife on her during an argument outside a strip club.
He previously served time in jail for violating his probation on an earlier assault charge.
