BATON ROUGE, La. -- LSU backup quarterback Danny Etling made his debut with the 21st-ranked Tigers count.Replacing struggling starter Brandon Harris on LSUs third possession, Etling opened with three straight scoring drives, and the Tigers pulled away for a 34-13 victory over Jacksonville State on Saturday night.Etling, a transfer from Purdue, completed six of his first eight passes for 100 yards, including a 46-yard scoring strike to tight end DeSean Smith to cap the quarterbacks first drive. Etling also had a 2 yard TD run.His performance could make him LSUs starter when the Tigers (1-1) open their Southeastern Conference slate at home against Mississippi State next Saturday. LSU coach Les Miles might not have much choice, considering how anemic LSUs offense looks with Harris under center, not just against JSU, but also in a 16-14 upset against fifth-ranked Wisconsin a week earlier.LSU opened the game with 12 total yards and no first downs on its first two offensive series before Miles made the QB change.The Tiger Stadium crowd came alive with Etling took the field for the first time. It was a full-on eruption when Etlings long scoring pass hit Smith in stride down the left sideline, giving LSU a 6-3 lead.Etlings performance was not entirely unblemished.

He was intercepted by Reggie Hall on a long pass intended for Malachi Dupre in the end zone and later lost a fumble when he was sacked and stripped by Darius Jackson.Leonard Fournette did not play, getting the night off to rest his left ankle, which took a hard hit at the end of LSUs season opener. Miles has said Fournette is not seriously injured.Derrius Guice started for Fournette and rushed for 155 yards rushing, including a 4-yard TD and a 44-yard run to set up another LSU score.A 2-yard touchdown run by BryKiethon Mouton capped Etlings third series.

He passed for 248 yards, including a 76-yard scoring pass to Krenwick Sanders, and rushed for 82 yards. JSU fields several transfers from top-tier Football Bowl Subdivision programs, including former LSU receiver Kevin Spears, who caught two passes for 51 yards.THE TAKEAWAYJacksonville State: Jenkins has the ability to put up big numbers on any defense, meaning his FCS-level opponents will have their hands full. Jenkins is easily on pace to eclipse the 10,000-yard mark in career total yards by the end of this season. He entered the game already holding the JSU record for total yards with 8,688.LSU: Barring an injury to Etling, Harris next snaps might come in mop-up duty.
