Sir Nick Faldo insists Tiger Woods may not ever be able to rediscover his best form after his career-worst round of 85 on Saturday.
The former world number one was left embarrassed on day three of The Memorial in Ohio after he failed to kick on after making the cut on Friday.
Woods looked a shadow of his former self as he found the water on four occasions on the last 10 holes.
He then finished his round with a quadruple-bogey and Faldo admitted after the round that Woods may not be able to carry on for much longer.
“For me, this has been going on a while,” he told the Golf Channel. “Three Masters ago, I was on the [practice] range watching Tiger hit beautiful fades and draws. He was hitting the ball fabulously. Then he walks to the first tee, two snap hooks.
“From that day on, I thought to myself, he’s not comfortable, he’s starting to fear shots. When you are fearing a shot before you hit it, we’re all in serious trouble.
“I’m not too sure how much more he can handle in all of this.”
