TIGER WOODS  ignores wheelchair bound half-bro despite repeated attempts at reconciliation.

Tiger's eldest half-brother, Earl Woods Jr. told ESPN  their other half-brother, Kevin Woods, 52, was diagnosed with multiple sclerosis in 2009, is wheelchair-bound, and is financially struggling.

And Tiger? MIA.

"I leave messages. I leave updates on Kevin, but for whatever reason I don't get a response. Kevin loves Tiger. A call from Tiger would really pump Kevin up. When he doesn't call, it just makes him feel worse," Earl Jr. told ESPN.

"We haven't asked Tiger for a dime. Not even tickets to a tournament. But Kevin's losing his home. He needs a caregiver and he can't have a caregiver and keep his home at the same time."

The only word from Tiger was a call back from his rep saying he was busy preparing for the Masters and would not be calling them back, RadarOnline.com reported.

"I'd like to (slap) Tiger, wake him up. I'd like to say, 'Don't come knocking on the door when you need a bone-marrow transplant.' To see this is the response we get?" Earl Jr. said.

"Maybe when you see the world like he does, you don't see what other people are going through. But, seriously? You've got problems with your knee? That's nothing compared to what Kevin is going through.
