Rangers starting pitcher Yu Darvish said Sunday he's not ready to throw a baseball two days after being scratched from his scheduled spring start due to a stiff neck. 

Manager Ron Washington said Sunday there is the possibility Darvish could throw a bullpen session on Tuesday or Wednesday before the Rangers leave Arizona. He could then throw one tuneup inning during the two-game exhibition series with Houston in San Antonio Friday and Saturday.

"I think we’ve got to wait and see how this issue progresses," Washington said, per The Dallas Morning News. "If not, we’ll go to a contingency plan. But I don’t want to say what that is yet."
