After nearly four years of litigation, a group of PGA Tour caddies have dropped their lawsuit against the circuit.
The lawsuit, which was filed in California in early 2015, centered on the bibs caddies wear during tournaments and ongoing attempts by the caddies to improve their healthcare and retirement options.
The caddies lost their class-action lawsuit in U.S. District Court and an appeal this year.
Separately, the Association of Professional Tour Caddies, which was not involved in the lawsuit but represents the caddies to the Tour, began negotiating with the circuit last year.
