Michael Young and Hank Blalock are both suffering from the bug that hit Ian Kinsler last night.
They are apparently both still planning on playing, but being under the weather and having to face Felix Hernandez isn't a real good thing.
And if both Young and Blalock were to be unable to play, the Rangers would have to call someone up from the minors, since the only backup infielder is Ramon Vazquez.
