Michael Phelps and Missy Franklin are expected to headline a host of U.S. Olympic medalists across three swim meets the first weekend of June in the last top-level domestic competitions before the U.S. Olympic Trials.
Phelps and Franklin are both scheduled to race at the Austin Elite Invite in Texas from June 3-5. Olympic 200m freestyle champion Allison Schmitt, a training partner of Phelps, and Olympic 100m backstroke champion Matt Grevers are also slated for that meet.
Phelps and Franklin last competed at a USA Swimming Pro Series meet in Mesa, Ariz., in mid April.
Phelps withdrew before a meet in Atlanta two weeks ago as his fiancée was set to give birth to their first child, a boy they named Boomer.
Franklin withdrew before the end of the Mesa meet on coaches orders because she was not feeling 100 percent, according to her social media.
Also the first weekend of June, Olympic champions Natalie Coughlin, Nathan Adrian, Dana Vollmer and Anthony Ervin lead the field for a USA Swimming Pro Series meet in Santa Clara, Calif.
London Olympians Connor Jaeger, Micah Lawrence and Shannon Vreeland headline the field for a USA Swimming Pro Series meet in Indianapolis from June 3-5.
Ryan Lochte and Katie Ledecky have not been announced for any of the three meets but could still compete before the Olympic Trials, which are June 26-July 3 in Omaha, Neb.
