Phil Mickelson will not be teeing off at this week's PGA Championship, dashing hopes for fans eager to see the six-time major champion return to the spotlight.

Originally listed in the field at Aronimink Golf Club, "Lefty" had been expected to make his major championship comeback after missing the Masters. But in early May, Mickelson announced his withdrawal, citing a "personal health matter with his family"—the same reason given for his absence from Augusta National.

At 55 years old, Mickelson remains one of golf's most decorated players, with two PGA Championship titles among his six major victories. However, his schedule has been sparse this season on the LIV Golf tour, where he has competed in just one of six events.

For now, the golf world is left wondering when—or if—Mickelson will return to competitive play. What's certain is that this weekend's PGA Championship will proceed without one of the sport's most beloved and polarizing figures.
