The former NBA star was airlifted to Los Angeles on Monday to continue his recovery at Cedars-Sinai Medical Center after spending a week at Sunrise Hospital in Las Vegas.

Doctors have reportedly asked for Lamar to not receive visitors until his condition improves, allegedly due to the procedures putting him in a "fragile mental state,” according to TMZ.
