The Colts suffered their first loss of the season after their passing attempt on fourth down was batted down in an overtime game in Loomis.
Cody Otten caught a touchdown pass on Del Oro's overtime possession then made the defensive play to stop Logan (5-1) on its attempt.
Warren Miles Long and Damond Beasley scored Logan's touchdowns as regulation ended in a 13-13 tie.
It was the first win of the season for Del Oro (1-4), who represented Northern California in last year's Division II state bowl game.
"We got everything we were looking for expect for the win," said James Logan coach George Zuber. "It was a great high school football game."
