Brooks Koepka said he can play through the pain in his bid for a third US PGA Championship but a full recovery from a knee injury remains months away.
Koepka has been plagued by injuries since winning back-to-back PGA Championships in 2019 and a fourth major title in three years.
The American star underwent knee surgery in March, having won the Phoenix Open, and he has missed the cut in his past two events, including last month's Masters.
As Koepka gears up for Thursday's opening round at Kiawah Island Golf Resort in South Carolina, the 31-year-old acknowledged his knee is still problematic but he is ready to play.
"I feel like I can hit every shot. It's not like Augusta where I'm trying to figure out what's the best line to walk instead of figuring out. Now I can actually hit golf shots and understand what's going on," Koepka, who has been paired alongside Justin Thomas and Rory McIlroy told reporters on Tuesday.
"For a while it was just I neglected putting just to see if I could hit shots, because if I can't hit shots I can't play. No point in that. No, I got everything under control and know what I'm doing. Last week was a good test just to see where I'm at for two days.
"I thought if I got four, it would be nice, but two days of rest didn't hurt me."
Asked for a timeline for him to be fully healthy, Koepka replied: "We're talking probably another six months."
"If I beat that, I'm doing something good," he continued. "I mean, I can play. You're never 100 per cent, that's the thing. For two straight years it's been left knee, right knee, herniated a disc in my neck, played in Tampa or wherever we were, played through that. I dealt with that all the way through Palm Springs.
"I can deal with the pain. That's not an issue. It's just a matter of being able to hit shots that I want to hit and do things I want to do, and I'm starting to be able to do that. Even though I'm not 100 per cent, I can still hit the shots."
Koepka added: "Every day has been a long day. Starting from just the training to the rehab, everything seems to take an hour, hour and a half longer, more attention to detail of what I'm doing off the golf course, make sure I'm doing -- I seem to get hurt in a bunch of freaky instances.
"It's just one of those things where you've just got to move past it and take it one day at a time."
