Former NBA player Lamar Odom's condition has reportedly worsened, giving him less chances of survival. He was found unconscious at the Love Ranch South brothel in Pahrump, Nevada, on Oct. 13.
"The doctors are concerned it has been too long that he's been in this condition and now it's not looking good," an unidentified source told TMZ.
Unidentified sources told the gossip site that Odom squeezed the hand of estranged wife Khloe Kardashian on Oct. 14, but doctors believe the squeeze may have been an involuntary muscle movement.
The sources say that Odom has not improved or regained consciousness, and four of his organs are failing.
Doctors reportedly gave the 35-year-old a 50/50 chance of surviving on Oct. 14.
An unidentified source told PEOPLE that Odom's estranged wife Khloe Kardashian, her sister Kim and mom Kris Jenner flew to Las Vegas on Oct. 13, and were told by doctors that "cocaine and opiates" had been found in Odom's system, but that has not been officially confirmed.
Khloe's sisters Kourtney and Kendall Jenner are said to have joined her at the hospital in Las Vegas.
"They're pretty sure this is goodbye, but they're praying for a miracle," the source added. "They know that God has the power to heal him, but that's really the last hope at this point. This is really bad."
It was previously believed and widely reported that Kardashian and Odom had divorced when they signed divorce papers in July, but a judgment has not been entered by a court, so technically the two are still married.
As a result, Kardashian is legally in charge of Odom's medical decisions.
"She never dreamed that she'd have these responsibilities, and it's just so overwhelming and unexpected," an unidentified source told PEOPLE. "She had been thinking of him as an ex, so to find out that, 'No, you have to do this.' Well that's really hard for her."
"Kris is giving some advice, but everyone else is basically just being there for her, letting her vent and talk about it," the source added. "But no one is going to tell her what she should do, because that's her decision."
Kardashian is reportedly flying Odom's father, his ex-girlfriend and two kids to Las Vegas to be with Odom.
