UNDATED (AP) — TCU quarterback Casey Pachall has been suspended indefinitely after he was arrested on suspicion of driving while intoxicated. Coach Gary Patterson announced the suspension Thursday morning, hours after police say Pachall was pulled over for running a stop sign near TCU’s Fort Worth campus. In February, Pachall admitted to police that he smoked marijuana and failed a drug test two weeks before his roommate was arrested in a sting operation. The 15th-ranked Horned Frogs, who are 4-0, host Iowa State on Saturday.
