Lamar Odom was scheduled to be transported by medical helicopter from Las Vegas to a Los Angeles hospital Monday night, sources told ESPN's Ramona Shelburne.
Odom was to be accompanied by his estranged wife, Khloe Kardashian, sources said.
The helicopter scheduled for Monday night is large enough to transport the 6-foot-10 Odom, after he had to be transported by ambulance last week because he was too tall for the helicopter to Las Vegas from a regional hospital in Pahrump, Nevada, near the brothel where he was found unresponsive.
Odom's family and friends said earlier Monday that his condition was improving.
