The 36-year-old basketball player is battling back to health after being found unconscious in a brothel last month and though his estranged wife Khloe Kardashian says he is "doing better", she admits he has both good and bad days.

She told 'Extra' presenter Terri Seymour: "He's definitely doing better, which is awesome. Every day is better, he's off of all machines that, he is alive on his own, and no machines are helping him, which is great, but he still has a lot of physical and cognitive therapy to go through, so it's a long road for him.

"It's gonna be a long long time. Every day is different -- some days he's really strong, and some days he's weaker than the day before 'cause it's mentally draining, I'm sure, on him."

While Lamar is getting better, Khloe doesn't think he will be able to leave hospital until he is able to move around unassisted.

Asked what happens next for the sportsman, she said: "He will try to learn how to walk... so that is first... When he can support himself on his own, or physically try to walk better on his own or at least with an assistance, with, like, a walker, then he will probably leave the hospital and do a lot of cognitive and mental strengthening."
