Anderson, who also connected on a 29-yard field goal in the first quarter, booted a 35-yard extra point strong and true a long attempt made necessary when Olympus was penalized for unsportsmanlike conduct after Ben Seagle on a 7-yard run with 8 minutes, 51 seconds remaining.
"I thought it was blocked at first when everybody was freaking out. It was a shock, but it was awesome," said Corner Canyon running back Riley Ogden, who finished with 88 yards rushing. "It was pretty scary there at the end, but I knew we could get it done,"
After losing its first three games this season, each by margins of a touchdown or less, Corner Canyon (2-3, 2-0) has won its first two games in Region 7 and handed Olympus (3-1, 0-1) its first loss of the season.
Chargers quarterback Michael Ebeling found Izaac Brinton for a 7-yard TD pass in the first period.
Ebeling broke loose from the Titans defense for a 7-yard scoring run on the first play of the fourth quarter.
That gave Corner Canyon a 17-3 lead, but Olympus rebounded quickly. Seagle's ensuing TD was set up in large part by a successful hook-and-ladder third-down play. Lineman Miles Henry-Davis caught the lateral and rumbled 26 yards to the Chargers' 15.
The last touchdown of the game came when Titans quarterback Chase Manning found Connor Haller from a yard out, but the extra point missed.
"That was a very good team we beat well-disciplined, well-coached," Corner Canyon coach Don Eck said. "They're two-time reigning region champs. It's a great win for this young program."
