In a contest filled with questionable calls, one kick may have been the biggest head-scratcher in LSU’s 20-13 loss Saturday night to No. 4 Alabama.

The Tigers took a 13-10 lead following kicker Colby Delahoussaye’s 39-yard field goal with 50 seconds left. But on the ensuing kickoff, sophomore Trent Domingue booted a low line drive that skipped out of bounds.

The penalty gave the Tide the ball on its 35-yard line, setting up a game-tying field-goal drive.

LSU coach Les Miles said the kickoff was supposed to go out of the back of the end zone. It was 15 free yards for an opposing squad simply looking to get into field-goal range.

Alabama did so, tying the game on sophomore Adam Griffith’s 27-yard field goal to send the game to overtime.

Delahoussaye said he’s tried to keep his fellow kicker in good spirits following the mistake.

“Yeah, I’ve been on Trent since I played soccer with him way back before this was even thought of,” Delahoussaye said. “He picks me up whenever I have a rough night. We have a real close brotherhood, and Trent’s an amazing kicker.”

Miles to ‘investigate’ personal foul

Instead of continuing LSU’s final fourth-quarter drive on second-and-goal at the Alabama 6-yard line, an unsportsmanlike conduct penalty on LSU junior left guard Vadal Alexander moved the Tigers back to the Crimson Tide 21-yard line.

Miles didn’t appear to agree with the call during his postgame news conference.

“I am going to want to look at the personal foul down on the goal line before I comment,” he said. “If one of my guys did that, I am going to tell him, and I am going to be up front. That is not what I am told, so I am going to investigate because that penalty changed the complexion of the game.”

Said quarterback Anthony Jennings of the flag: “That was huge. It’s a lot of pushing and shoving going on throughout the game. A lot of emotions.”

Collins’ return a success

There may not have been a player more elated to leave Tiger Stadium with a victory than Alabama junior safety Landon Collins.

The New Orleans native, former Dutchtown standout and one-time top safety recruit in the nation chose the Crimson Tide over LSU in 2012, a decision frowned upon by his mother during the 2012 Under Armour All-America Game.

Collins remains undefeated in Death Valley after two trips. He finished Saturday night with seven tackles.

“I’m speechless,” he said. “It’s the best win of my life. When overtime took over, we did our job and played excellent.”

Hilliard’s shoulder injury

LSU running back Kenny Hilliard started the game against Alabama, but he didn’t finish it.

Hilliard suffered a shoulder stinger in the first half, according to reports from CBS and the LSU radio broadcast. Miles didn’t release details of Hilliard’s injury after the game, aside from calling it a shoulder injury.

Hilliard had three carries for 15 yards — all in succession on LSU’s first drive. He appeared to be injured on his final carry, a 6-yard run that picked up a first down.

In the polls

LSU dropped to No. 20 in the Associated Press Top 25 and the coaches’ poll.

The Tigers (7-3, 3-3) dropped six spots in the AP poll and five in the coaches’ rankings. The Crimson Tide (8-1, 5-1) moved up a spot to No. 3 in the coaches and remained at No. 4 in the AP.
