Woods, who made it all the way back from four surgeries on his back in recent years, has played only 10 times this season.
Tiger Woods' first round of the 2019 FedEx Cup Playoffs at The Northern Trust is not off to a good start, but at least there aren't very many people there to see it. "I've said in the past, years ago, he just would have continued to play through all of this". But he has said on numerous occasions that although his spine is fused, the "force has to go somewhere", and that it leads to some other issues he has experienced. "My iron game, which is usually the strongest part of my game, was off.my distance control was off".
Thursday's round captured his struggles.
But it is the second time this year injuries have prevented Woods from playing, with the 43-year-old pulling out of the Arnold Palmer Invitational in March - although that was several days before the tournament and not an official withdrawal. That was after he tried, and almost succeeded, to drive the green on the 303-yard, par-four 16th.
Woods is now 28th on the FedEx standings and is already guaranteed to context the event at Chicago's Medinah Country Club, where Woods won the 2006 US PGA Championship.
Woods' appearance this week in New Jersey was his first tournament since missing the cut last month at The Open Championship.
"I'm going to have to figure out a way to get this thing under par (on Friday)", he said. After his opening round, he said his back was "a little stiff, but that's just the way it's going to be".
"It gives you confidence the rest of the day and they just kept going in".
