Neither Korir nor Arop have entered the Commonwealth 800m, but world 1500m champion Jake Wightman will step down in distance to the two-lap race for the Birmingham Games, where he will represent Scotland.
After finishing fourth in the final, Emmanuel Wanyonyi will spearhead the three-pronged Kenyan challenge in England.
“You just have to reset as fast as possible; there’s no choice,” Bol said.
“The results will show in Birmingham whether it works out or not, but I’m willing to give it a shot.”
Australian No.1 Liz Clay suffered a heavy fall in the opening round of the women’s 100m hurdles, putting her Commonwealth Games campaign in grave doubt.
Clay, 27, was taken straight to the medical room after clattering into the seventh barrier in her heat and crashing to the track.
She was scheduled to have an X-ray on her left foot on Saturday night in the US.
In much better news, Australians Michelle Jenneke and Celeste Mucci both advanced to the semis.
Jenneke was particularly impressive, clocking 12.84 in a heat also involving world record holder Kendra Harrison from the US.
“I am ecstatic with that,” Jenneke said.
“I’ve come into these championships with one real goal and that’s to run a PB.
“I didn’t quite get that today but to be that close, just 0.02 off my best and I think my PB was with a 1.2m tailwind and today was into a small headwind.
“I don’t think I executed the end of my race that well so there’s still some time there.”
Mucci clocked 13.01 while Nigerian Tobi Amusan topped the timesheets with an African record time of 12.40.
Australian record holder Brooke Buschkuehl needed only one qualifying jump to advance straight through to the women’s long jump final.
Buschkuehl – who broke her own Australian mark last week with a huge jump of 7.13m in California – managed 6.76m in Eugene, just over the automatic qualifying mark.
Fellow Australian Samantha Dale (6.04m) was eliminated.
Ash Moloney improved his position from 10th to fifth at the halfway stage of the decathlon after clocking an impressive 400m time of 46.88 to close out day one.
The Tokyo Olympics bronze medallist remains in contention for another podium position, especially after Olympic champ Damian Warner from Canada pulled up midway through the 400m clutching his left hamstring.
Ayden Owens-Delerme from Puerto Rico was in the gold-medal position with 4606 points.
Moloney had 4378 points, with fellow Australians Cedric Dubler (4286) and Daniel Golubovic (4065) in 10th and 18th places respectively.
