10:58AM EST October 4. 2012 - TCU starting quarterback Casey Pachall was arrested and charged with DWI early Thursday.
NBCDFW.com cited a Fort Worth police report that stated the junior ran a stop sign and hit a curb before being pulled over.
The arrest could signal discipline against Pachall. He previously has admitted to using marijuana as part of a campus-wide drug bust that led to the dismissal of linebacker Tanner Brock, who was Pachall's rooomate.
TCU confirmed this summer Pachall failed a drug test, but he was not suspended.
In four games, Pachall has thrown for 948 yards and 10 touchdowns. The 13th-ranked Horned Frogs faces Iowa State on Saturday.
