Oklahoma State Coach Mike Gundy Informed the Media that starting QB J.W. Walsh will remain in a boot until tomorrow when he will further evaluated.
Translation: "I'm not talking about this in the weekly press conference, so don't ask."
Hopefully we will find out more to the extent of Walsh's injury this afternoon, but it's unlikely. Oklahoma State typically doesn't release injury information unless it's clear the player is out for the season. Even then you can't rule out a possible return.
