It’s unlikely that TCU quarterback Casey Pachall will return to the field Saturday against Texas, but he has not been ruled out, TCU coach Gary Patterson said Tuesday.Pachall broke his left arm Sept. 7 against Southeastern Louisiana. He has not had his weekly doctor’s visit, Patterson said. Should Pachall be cleared to play, Patterson said, the school will release the information by Friday.TCU (3-4, 1-3 Big 12) hosts Texas (4-2, 3-0) at 6:30 p.m. Saturday at Amon G. Carter Stadium. Pachall returned to the practice field before the Oklahoma State game as the scout team quarterback, and Patterson said he believed that Pachall will return this season.The coach also poured his trust into sophomore quarterback Trevone Boykin.“I wouldn’t trade Trevone Boykin, to be honest with you, for anybody, from what I see in practice,” Patterson said. “The key is we have to see it in a ballgame.”Boykin has thrown for 1,152 yards and five touchdowns, completing 58.8 percent of his passes. Known for his ability to scramble, Boykin has rushed for 293 yards and three touchdowns on a team-leading 86 carries.But TCU continued its string of poor first-half offensive performances in its 24-10 loss at Oklahoma State, putting Boykin, the offensive line and offensive coordinators in the spotlight for offensive ineffectiveness. Patterson pointed the finger of blame at himself.“To me, you don’t blame assistant coaches anyway,” he said. “You blame the head coach because he’s the one in charge of making sure it gets run anyway. For us, it’s a lot of people because of the way the offense has been, but what I have to say to those people is it’s a lot of factors.”The real McCoyNews spread quickly Monday of Texas quarterback Case McCoy’s take on why the Longhorns are the Vegas underdogs against TCU.“Probably because I’m the quarterback, right?” McCoy told reporters in Austin on Monday.Gary Patterson defended McCoy on Tuesday.“I think he’s a good player. I don’t know why he would say that. He’s reading too many blogs,” Patterson said. “The way you judge a quarterback is if he’s won or lost and since he’s been a starter [in Big 12 play] they’re 3-0.”McCoy took the starting job from David Ash first in Texas’ game against Ole Miss, then again in the second half of the Kansas State game when Ash suffered concussion-like symptoms. McCoy, a senior from Graham, has thrown for 764 yards and four touchdowns, completing 61 percent of his passes. “He’s getting the ball into the hands of his receivers and he’s handing the ball off and he’s checking plays he needs to get done what he needs to get done,” Patterson said. Injury reportJunior wide receiver Cam White is questionable for Saturday’s game after suffering a head injury over the weekend off the playing field.Gary Patterson said White slipped while playing with his child on Sunday, hitting his head. He wouldn’t say if it was a concussion-related injury.Also, Patterson said sophomore tight end Dominic Merka is out for the season with a broken leg suffered in Saturday against Oklahoma State. Offense ralliesSenior lineman James Dunbar called together the TCU offense over the weekend for a players’ meeting to discuss its lack of production, Gary Patterson said.Dunbar has regularly been a captain for the Horned Frogs this season and can be seen before every game in the middle of the players, leading the team’s pregame hype. “There isn’t anyone here kid-wise, besides the freshmen, that hasn’t been through it and isn’t trying the best they can,” Patterson said.
