STILLWATER, Okla. — TCU coach Gary Patterson promised changes if the offense didn’t start to show signs of breaking out of its season-long struggle. After another sputtering start Saturday against Oklahoma State, change started to come on and off the field.Redshirt freshman Tyler Matthews replaced Trevone Boykin at quarterback after Boykin’s second interception. Matthews took over at the TCU 19 with 3:33 left in the first half, and it wasn’t exactly a rousing start. On his first play, his handoff to Ty Slanina on a jet sweep was fumbled and recovered by the Cowboys. The turnover didn’t lead to any points as OSU missed a 31-yard field goal attempt after a strong stand by the Horned Frogs’ defense. Matthews played one more full series, TCU’s last of the first half, and replaced Boykin, who took some hardt hits, for only for a couple of plays in the second half. Matthews’ one pass attempt was incomplete. He rushed three times, netting two yards.Patterson declined to offer a reason why Matthews didn’t start the second half.“Because Trevone did,” he said.Another change for the offense was having co-offensive coordinator Rusty Burns take the lead in calling plays in the second half. Patterson said the plan was hatched earlier in the week. Also, co-offensive coordinator Jarrett Anderson moved down to the sideline from the booth for the second half. Patterson moved him to the booth after the Texas Tech loss Sept. 12.“We needed someone to get them fired up so Coach Anderson was back down on the field so we could get [the plays] in faster,” Patterson said. “They still worked together just like before. “Sometimes you just need somebody else … how they think about it. They both still had calls. We had guys open. We’ve got to go make plays.”Oklahoma bluesThe state of Oklahoma hasn’t been kind to the TCU offense in 2013. In two first halves against the Sooners and Cowboys, the Frogs have been shut out, punted 12 timesand gained only 78 yards of total offense. TCU has thrown two interceptions and fumbled once. Injury updateSpecial teams player and tight end Dominic Merka broke his leg in the first half and will not return this season, Gary Patterson said. Receiver Brandon Carter suffered an unspecified injury and did not play in the second half, and defensive tackle Davion Pierson suffered a leg injury in the first half and did not return.Briefly• TCU lost for only the second time in its last 37 games when it’s had at least three takeaways.
