Via twitter:
I need time to recover and I am really sorry for my Japanese fans, but I will come back to Tokyo, unfortunately not this weekend.
I am training in the countryside of Ethiopia and fell, that happens more often but this time with my knee on a stone. Bad, bad luck for me.
I am really disappointed that I have to withdraw from Tokyo Marathon, I was feeling great in training.

Kind of disappointing news given Haile's recent history; I hope he still makes a comeback.
