ARLINGTON — TCU thought it had completed a goal-line stop to end the first half. Officials had issued a 10-second runoff after an LSU player’s helmet came off during a third-and-12 play with 5 seconds leftAfter referee John O’Neill of the Big Ten made the call, TCU quickly huddled and headed into the tunnel at AT&T Stadium. That’s when the chaos began.O’Neill quickly flicked on his microphone to correct the crew’s mistake. Because the play in question stopped the game clock on an incomplete pass, LSU would have a fourth-down opportunity with 5 seconds left.LSU quickly assembled its field-goal unit to try a kick that would give the Tigers a 16-10 lead heading into the locker room, but only two TCU players remained on the field.TCU defensive tackle Chucky Hunter, one of those two players, was issued an unsportsmanlike conduct penalty, giving LSU a first down and moving the ball to the 6-yard line.Eventually, TCU made its way back on the field. An enraged TCU coach Gary Patterson went onto the middle of the field to issue a few choice words for O’Neill.When the field cleared, LSU kicker Colby Delahoussaye drilled a 23-yard kick as time expired.During halftime, the refereeing crew issued a statement regarding the call on the 10-second runoff.“When a helmet comes off and that’s the only thing that stops a clock, that’s an opportunity for a 10-second runoff under one minute of either half. In this case, we had two things that stopped the clock: the helmet off and an incomplete pass. As a result, that does not qualify for the 10-second runoff.”Record-breakerWith TCU trailing 13-3 early in the second quarter, B.J. Catalon scored TCU’s first touchdown of the season on a 100-yard kickoff return. It followed J.C. Copeland’s 1-yard touchdown run for LSU.The return set an AT&T Stadium record for a kickoff return in a college game. It was also the first 100-yard kick return for the Frogs since Cory Rodgers did it against BYU in 2005.The return ranks second in TCU history behind Charles Casper’s 105-yarder against Texas in 1933.Catalon took Brandon Carter’s place at kick returner after Carter fumbled LSU’s first kickoff in the first quarter.Verrett adds a sackTCU preseason All-American Jason Verrett added a first on Saturday by recording a sack on LSU quarterback Zach Mettenberger in the second quarter.Verrett was untouched blitzing from the left. He wrapped the quarterback up and eventually slung him to the turf.The cornerback led TCU in tackles in the first half, recording six, four of which were unassisted.Drawing a crowdAn attendance of 80,230 marked the third-largest crowd for the Cowboys Classic and the sixth-largest crowd in AT&T Stadium history.
