Jarrett Stidham, Kyle Davis

In this Saturday, Sept. 30, 2017, file photo, Auburn quarterback Jarrett Stidham (8) and wide receiver Kyle Davis (11) celebrate with fans after defeating Mississippi State 49-10.

Two Matchups To Watch

Auburn RG Braden Smith vs. LSU D-line

An All-American a year ago, Smith cuts the path for Auburn’s spread rushing attack. LSU coach Ed Orgeron called him “one of the best linemen in America.” DE Christian LaCouture battled Smith last season in an 18-13 LSU loss on the Plains and describes the guard as an athletic player with good hands who can “knock you off the ball.”

Auburn QB Jarrett Stidham vs. LSU secondary

DBU will get tested by the SEC’s most efficient passer. The ex-Baylor QB completes 71.2 percent of his passes, fifth nationally, with seven touchdowns and just two interceptions. The Tigers’ DBs have made a transition over the past two weeks, with coaches moving Donte Jackson inside to nickel. The new look’s first real test comes Saturday.

LSU: Keep An Eye On No. 97

The Tigers return DE Frank Herron after a presumed six-game suspension, and the fifth-year senior should boost a unit low on depth. He’ll likely see 20-25 snaps, spelling starters Christian LaCouture and Rashard Lawrence.

Auburn: Keep An Eye on No. 21

Kerryon Johnson has usurped injured Kamryn Pettway as AU’s lead tailback. The No. 1-ranked prospect in Alabama in 2015, Johnson is averaging 6 yards a carry and has scored a nation-leading 12 touchdowns, the same number LSU has scored as a team.
