If Boro progress in both the Carling Cup and FA Cup the Yak would have potentially missed upto nine Boro games, but his decision will be a great relief to Steve McClaren and the supporters alike.
The 23-year-old and the Nigerian coach, Austin Eguavoen, do not see eye-to-eye.
"Unfortunately, I do not have a good relationship with our national coach, Austin Eguavoen. We are not on good terms, so I think it is best that I don't go." said Yakubu.
"He is not happy with me and I am not happy with him.
"I would love to go there and play for Nigeria. It would mean a lot to me to play for my country there because it is a prestigious tournament for African nations.
"It was a big decision for me but I have made the right one."
