AVONDALE, La.

PGA Tour star Jason Day expects to arrive in Augusta, Georgia, on Friday to start practicing for the Masters, but said he could pull still out of the season’s first major, depending on his mother’s prognosis following surgery for lung cancer last week.

“Obviously, I’m still nervous because we’re still waiting to see … if it has spread or not,” said Day, who spoke Monday on a video conference set up by organizers of the PGA Tour’s Zurich Classic in late April. “From there, we have to kind of come up with a game plan whether to go chemo — a form of chemo radiation — or something else.

“It’s still kind of a bit of an emotional time for me,” added Day, whose father, Alvin, died of cancer when he was 12. “Obviously, I’ve been hanging out with my mom a bit and seeing her and she’s recovering well. She’s a tough lady, but it’s hard because I look at her and she’s on the pain killers and all that stuff, what she needs to do to recover … but I can’t help but think of my dad when I see her in that situation.”

The world’s third-ranked golfer revealed that his mother, Dening, has cancer after withdrawing from the Dell Technologies Match Play in Austin, Texas, last Wednesday.
