The big news from round 1 of the 1500 this morning was that Ayanleh Souleiman left the track on a stretcher. He was running fine, mid pack, started hobbling a bit with 480 meters to go, pulled up and soon was stretchered off the track.
Souleiman is the world indoor 1500 champ and got a bronze at 800 at the last worlds. As noted in this thread:

Matt Centro's strong medal chances increased.
It was a good day for the Americans as all 3 Americans made the semis. Matt Centrowitz and Leo Manzano automatically and Robby Andrews on time. Centro looked the best. Andrews looked to have the wheels to make it on time but got boxed in.
