Phil Mickelson just lost a major sponsor in the wake of his controversial comments on Saudi Arabia ... and it's one of his oldest partners.
Callaway Golf is pausing their business relationship with the pro golfer and will stop sending him payments.
The golf company says they will reevaluate the partnership at some point in the future ... but for now, they are distancing themselves from Phil.
As you know ... Mickelson is catching a ton of heat for his comments on Saudi Arabia ahead of playing in a new golf league in the country.
