Because of stiff back, not related to previous injury.
Justin Verlander has been scratched from Wednesday's scheduled start versus the Indians due to mid-back stiffness.
The Tigers aren't overly concerned, as this looks like a precautionary move. The hope is that Verlander will be able to start at some point over the next five days. Buck Farmer has been recalled and will fill in for Verlander on Wednesday.
