Jarrod Lyle has admitted he will be struggling to keep his emotions under control when he tees off in this week's Australian Masters.
The 32-year-old is playing in his first tournament for 20 months after undergoing treatment for cancer despite being unsure if he is physically ready to complete 72 holes.
Lyle was diagnosed with myeloid leukemia in March last year having previously battled the same disease as a teenager.
But he is determined to give a good account of himself at Royal Melbourne, although he knows his opening tee shot will be the most difficult of his career.
"Just walking to that first tee and teeing the ball up and trying to hit it that's probably going to be the hardest thing," said Lyle, who remains a member of the PGA Tour on a medical exemption.
"It's just going to let a whole lot of stuff out. Hopefully when that ball flies I can just get on to playing golf and put everything behind me and just get back to the golfer that I am.
"I'm going to dedicate this first tee shot to everybody that's done that over the years or over the last 20 months. Everyone who has got in contact with us and given us support."
Lyle's plight has earned support from a number of his fellow professionals including Tiger Woods, who wore a "Leuk the Duck" pin in his cap when he won the Arnold Palmer Invitational in March.
The cartoon duck is the mascot for the children's cancer charity Challenge, which Lyle has become heavily involved with during his treatment.
"To have the support of all those guys, guys that I am not really close with as well, it is nice," Lyle said at the time. "It is nice to know they still care and want to know how you are going."
