The next installment of the Usain Bolt–Justin Gatlin rivalry may have to wait until the Rio Olympics, should they both make it there.
Bolt and Gatlin are expected to be part of the Jamaica and U.S. 4x100m relays for their final appearances at the World Championships on Saturday (NBC and NBC Sports Live Extra coverage, 2:30 p.m. ET).
But their next individual head-to-head race isn’t scheduled yet. There are two Diamond League season meets left this year — Zurich on Thursday and Brussels on Sept. 11.
Bolt hasn’t signed up for Zurich, his manager said.
