"Hopefully, what our plan is that he [Pachall] gets himself right and keeps the door open for us as far as an opportunity for him to be able to come back here and enroll in the spring," Patterson said.
Pachall was arrested on suspicion of driving while intoxicated after running a stop sign near the TCU campus last Thursday. That came eight months after Pachall admitted to police that he smoked marijuana and failed a team-administered drug test just two weeks before former linebacker Tanner Brock, his roommate and teammate then, was arrested in a drug sting with three other players and other TCU students.
Filling in for Pachall, redshirt freshman Trevone Boykin was 23-of-40 passing for 270 yards with a touchdown and three interceptions in Saturday's 37-23 loss to Iowa State. That ended the Frogs' FBS-best 12-game winning streak and knocked them out of the Top 25.
TCU (4-1, 1-1 Big 12) plays at Baylor (3-1, 0-1) on Saturday.
