For the seventh time in eight years, Edna Karr will be making the trip from Algiers to the Mercedes-Benz Superdome.

Or as Cougars' quarterback Skyler Perry calls the Dome....

"We're headed home."

Karr, the defending Class 4A state champion, will get a chance to go for the school's first repeat title after edging Warren Easton 20-12 in a semifinal thriller Friday before a standing-room-only crowd at Behrman Stadium.

No. 1 Karr (13-1) will play No. 2 Lakeshore (14-0) at 3:30 p.m. next Saturday in an all-New Orleans area championship game.

The Cougars will be going for their fourth state championship after winning titles in 1993, 2012 and 2016.

It was Karr's second win of the season over No. 4 Easton (10-3).

But this one was much closer than Karr's 40-6 victory in the regular-season finale that gave the Cougars the District 9-4A title.

"We knew based on last game that this was going to be a four-quarter game," Karr coach Brice Brown said. "In the first half we made a lot of uncharacteristic penalties and a lot of mistakes and missed execution. We said in the second half the cooler heads would win a hot game, and we settled down and made plays when we had to."

One of the biggest plays came with just 1:39 left when junior running back Ronnie Jackson scored on a 7-yard run to give the Cougars' an 8-point cushion late. It came after a pair of big runs by Ahmad Antoine. 

Easton still had one more chance, driving to midfield before Damien Tate, dominant on both sides of the ball, fumbled after catching a short pass from Lance Legendre.

"Penalties and turnovers hurt us," said Easton coach Jerry Phillips, a Karr alum. "We left it all on the field. At the end of the day, that's all I can ask. It was a good competitive game, and we just have to move on from here."

Jackson finished with two touchdowns for the Cougars. He had the game's first one on a 2-yard run with 30 seconds left in the first quarter. It came just one play after the Cougars converted a fourth-and-6 when Perry connected with Anthony Spurlock for a 33-yard gain.

Easton tied it late in the half when Legendre scored on a 32-yard quarterback keeper. Legendre had scored on a 48-yard run one play earlier, but it was nullified by a blocking-in-the-back penalty.

The Easton defense also forced two turnovers in the first half. Joshua Williams forced a fumble that Tate recovered in the first quarter, and Chester Kimbrough intercepted a Perry pass that led to the Eagles' first score.

But the game was tied 6-6 at halftime.

"We knew we just had to keep fighting," Jackson said. "The game isn't over until the clock says zero. So we just kept fighting to get that win. We are going back (to the Dome) to get that jewelry."

Easton took a 12-6 lead in the third quarter on a spectacular 27-yard catch by Yo'Heinz Tyler.

But it was the Eagles' last touchdown of the game and of the season.

"Defense has been the staple of this program," Brown said. 

Karr answered in the fourth, taking the lead for good when Anthony Spurlock came up with a highlight reel 28-yard catch of his own.

Then Jackson sealed it late, sending Brown to his third state title game in three seasons as head coach at his alma mater.

"Hats off to Warren Easton," Brown said. "They played a helluva game. Our guys came out and fought and played Karr football. My guys just wanted it a little bit more."
