Dunbar, a 2009 Kodiak High School graduate, placed sixth in the first of two preliminary heats with a time of 3 minutes, 45.33 seconds.
His time ranked 16th out of 28 runners.
The top four runners in each heat, plus the next four fastest times qualified for Saturday’s finals.
Dunbar ran in the slower of the two heats and just missed finishing in the top four of his heat by .26 seconds.
Pat Casey of the Oregon TC Elite won the first heat in 3:44.41, while Leonel Manzano took the second heat in 3:42.01.
Dunbar, who just completed his senior season at the University of Oregon, is scheduled to compete in the 5,000-meter finals at 8:25 p.m. today.
Earlier this month, Dunbar helped the Oregon men capture the national championship with a pair of top 5 finishes in the 5,000 and 10,000.
