Seattle Seahawks Running Back -- Arrested for DUI

Seattle Seahawks running back Spencer Ware -- don't worry, he's not really a factor -- was arrested for drunk driving early Sunday morning in Washington.

Ware -- a 22-year-old rookie from LSU -- has been on injured reserve since October after busting his ankle.

But cops in WA say he got behind the wheel of a car early Sunday morning and drove while intoxicated.

He was booked around 2AM ... and released a short time later on a $1,000 bond.
