Lamar Odom has shown no signs of consciousness or improvement two days after being admitted to the hospital.

Four of Odom's organs, includes his kidneys, continue to fail.

"The doctors are concerned it has been too long that he's been in this condition and now it's not looking good," said a source.

Doctors reportedly gave Odom a 50/50 chance of survival on Wednesday.

ESPN's Ramona Shelburne reported late Wednesday evening that Odom had made some small improvements.
