CORALVILLE, Iowa (AP) — The U.S. wrestling team will find out this weekend which 18 athletes will be eligible for the Summer Olympics. Half of the wrestlers who make the team might not make it the Rio.

The Americans find themselves in a precarious position as Olympic qualifying draws to a close. The U.S. has earned Summer Games spots in just nine of 18 classes ahead of the Olympic Team Trials, which start Saturday in Iowa City.

The U.S. still has plenty of chances to add Olympic berths in upcoming tournaments in Mongolia and Turkey. So for many of the wrestlers who win team spots this weekend, the path to Rio De Janeiro will have just begun.
