In a surprise development, Texas quarterback Matt Schaub is out for Sunday’s home opener against the Colts.

Per NFL.com, Schaub has a stomach problem.  Sage Rosenfels gets the start.

Per the AP, Schaub spent the night in the hospital, which required intravenous fluids.

Here are the inactives for the Colts-Texans game.

Colts inactives: S Bob Sanders, LB Buster Davis, T Corey Hilliard, G Daniel Federkeil, WR Roy Hall, TE Jacob Tamme, DT Daniel Muir, DE Marcus Howard.

Texans inactives: RB Chris Taylor, FS Will Demps, LB Xavier Adibi, G Kasey Studdard, T Rashad Butler, TE Mark Bruener, DE N.D. Kalu, DT Frank Okam. 

The list of inactives doesn’t include Schaub, probably because he and Rosenfels are the only two quarterbacks on the roster.
