ATLANTA -- Six spectators at the PGA Tour Championship in Atlanta on Saturday were injured when lightning struck a tree on the course.

The lightning strike -- one of two to hit the course -- connected with a tree near the 15th green/16th tee during the suspension of play, and the debris from the strike injured four nearby people. EMT tended to the fans and two others and transported them from the East Lake Golf Club via ambulance for further medical attention.

Play had been suspended as a result of the inclement weather at 4:17 p.m. ET; the lightning strikes occurred at 4:45 p.m.

The injuries do not appear to be life-threatening, the PGA Tour announced in a statement.

"The safety of our fans, players and partners is of the utmost importance," the PGA Tour said. "We will provide further updates as they become available."

As a result of the incident, play during the third round of the tournament was called for the day and will resume Sunday morning. Justin Thomas leads Northern Ireland's Rory McIlroy and Brooks Koepka by one shot through five holes.
