ARLINGTON — Arlington Lamar survived Friday night at Cravens Field for a 27-21 season-opening win over Richland.Rebels receiver Adrien Itoka scored an apparent game-tying touchdown with 1:22 left in the game, but the play was ruled a fumble before the senior broke the plane of the end zone. The Vikings hopped on the loose ball to preserve the win.Lamar (1-0) took its first lead of the second half early in the fourth quarter when quarterback Shane Buechele found the corner of the end zone on a 1-yard run, capping a 10-play drive with 9:21 to play. The junior finished with 159 yards through the air, one passing touchdown and the one score on the ground. But he was also shuffled in and out of the game with backup Andy Guinn after taking a pair of hits in the second quarter. Richland’s defense came up with a big stop with just under four minutes remaining to give the Rebels (0-1) one last opportunity. But it was Richland’s offense that set the pace in the first half. Quarterback Eddie Thomas threw for a score and rushed for another to lead the Rebels to a 21-20 halftime advantage. He finished with 159 yards through the air and 74 on the ground. But Lamar held Richland scoreless in the second half with strong play from the secondary.
