October 19 was quite a day for the longtime team of Phil Mickelson and his caddie, Jim "Bones" Mackay.
On that day, Mickelson had surgery for a sports hernia, while his looper went under the knife for a double-knee replacement surgery.
There may be no tandem in golf more in tune with one another, but Golf Digest reports that the timing of both surgeries was nothing more than a funny coincidence.
"We didn't even talk about it. We were both in a hurry to get it done, and it just happened to be the same day," Mackay told Golf Digest. "The next day we were texting back and forth. 'So, how are YOU doing?'"
Mackay has been bothered by knee pain for years, which -- as you probably guessed -- isn't ideal for someone who makes a living walking long golf courses most days of the week and then spends time cramped up on airplanes getting to the next stop when not looping.
"The doctor told me that what they found was definitively worse than they thought it was," Mackay explained to Golf Digest. "Forget about being a caddie, he said, basically my knees did not fit together well at all. If I hadn't gotten it done, I was probably risking something happening during the season and then being out a long time."
Mackay said that doctors are happy with his progress thus far and his goal is to return to Mickelson's bag for the CareerBuilder Challenge in Palm Springs, Calif., on Jan. 19 -- Mickelson's first scheduled start of the new calendar year.
