South Carolina knocks off Missouri in SEC play.

COLUMBIA, Mo. (AP) — Deebo Samuel ran for two touchdowns to help South Carolina cruise to a 31-13 victory over Missouri on Saturday night in the Southeastern Conference opener for both teams.

Missouri (1-1, 0-1) led 10-0 early in the second quarter when tight end Jason Reese slipped past linebacker T.J. Brunson, hauled in a Drew Lock pass and outran his pursuers. South Carolina (2-0, 1-0) trailed for only 30 seconds. Samuel returned the ensuing kickoff 97 yards for a touchdown — his second TD return in two weeks. After the Gamecocks' Jamyest Williams intercepted Lock, Samuel struck again, scoring on a 25-yard jet sweep. Samuel finished with five catches for 45 yards.

Jake Bentley was 18 of 28 for 187 yards passing and threw a 39-yard touchdown pass to Hayden Hurst to stretch South Carolina's lead to 21-10 midway through the third quarter. Hurst added a 2-yard scoring run in the fourth quarter.

Lock had 245 yards passing and a touchdown, but was intercepted twice. No. 3 CLEMSON 14, No. 13 AUBURN 6 CLEMSON, S.C. (AP) — Kelly Bryant had two touchdown runs after getting knocked hard to the ground and defensive end Austin Bryant had four of Clemson's 11 sacks in the No. 3 Tigers' 14-6 victory over Auburn on Saturday night.

This was billed as an early showcase between elite teams with dreams of the College Football Playoffs. Instead, Clemson's Bryants never gave Auburn (1-1) much of a chance.

Bryant, making his second career start at quarterback for defending national champion Clemson, appeared to be seriously hurt after he remained on the ground on a hit by Dontavius Russell. But after a few moments in the medical tent, Bryant returned to direct a pair of touchdown drives that gave Clemson (2-0) the lead for good.

"I just had the wind knocked out of me. I was fine," Kelly Bryant said. "I wasn't going to go out like that."

Bryant's 3-yard run right before halftime put Clemson ahead 7-6. He finished the next possession with a spinning, 27-yard burst .

Clemson's defense squashed any chance of an Auburn comeback. Bryant was nearly unblockable and created havoc quarterback Jarrett Stidham and Auburn, which was held to 117 yards.

Austin Byrant sacked Stidham on Auburn's final two plays as the Baylor transfer desperately tried to get the ball downfield. Byrant threw for 181 yards on 19-of-29 passing. He also rushed for 68 yards.

"Football players are tough-minded people," Austin Bryant said. "This just shows we were the most prepared team."

No. 12 LSU 45, CHATTANOOGA 10. BATON ROUGE, La. (AP) — Derrius Guice ran for 102 yards and two touchdowns, D.J. Chark returned a punt 65 yards for a score, and No. 12 LSU overcame bouts of sloppiness in a 45-10 victory over Chattanooga on Saturday night.

Danny Etling passed for 227 yards and a TD, connecting on eight of 14 attempts in less than three quarters of work for the Tigers (2-0). Etling's scoring pass was a 36-yarder to Drake Davis, who had only one career catch before that.

Chark had three receptions for 103 yards, including a 48-yard catch from Etling in the third quarter. Chark also had a 79-yard punt return for a wouldbe TD negated by a holding penalty.

While LSU coach Ed Orgeron is bound to be pleased overall by a twogame start in which the Tigers have outscored opponents 72-10 combined, he also could be concerned about a rash of penalties and place-kicking problems as his team prepares for its first Southeastern Conference game next week.

LSU was penalized 11 times for 74 yards, one week after committing 10 penalties for 86 yards against BYU.

Several early penalties helped Chattanooga (0-2), a member of the NCAA's second-tier Football Championship Subdivision, drive inside the LSU 10 on the game's opening series for an early 3-0 lead.

The Tigers scored the next 42 points — with senior Darrel Williams scoring twice on rushes of 4 and 3 yards.
