But Bird is not ready to concede the season, despite the prognosis.
“In nearly four months since first injuring my ankle, it had been increasingly frustrating to have only questions and no answers,” Bird said in a statement.
“All this time, I have wanted nothing more than to be out there playing the game I love as a member of the New York Yankees.
“My season is not over. I plan to do everything in my power to return and help our team win in 2017.”
A specialist confirmed Monday that Bird has a condition called Os Trigonum Syndrome, which is excess bone growth in Bird’s foot.
Despite showing little ability to stay healthy, Bird seems confident he can return.
