The PGA Tour has suspended the 17 members who are competing in the inaugural LIV Golf event, it announced Thursday.
Players who resigned their membership before starting the LIV Golf event being held outside London that began Thursday are also no longer eligible to compete in tour events or the Presidents Cup.
The memo said players who compete in LIV events are ineligible to participate on the PGA Tour or any other tours it sanctions, including the Korn Ferry Tour, PGA Tour Champions, PGA Tour Canada and PGA Tour Latinoamerica.
Monahan wrote that any players who take part in future LIV Golf events will face the same punishment.
