Woods, along with Ryder Cup rival Rory McIlroy, lipped off the pace after the second round of the BMW Championship yesterday.
The duo both carded opening rounds of 62 but finished the second day five and four shots adrift of new leader, and Ryder Cup hopeful, Xander Schauffele.
“I hit it just as good and putt it just as good. Nothing went in. That’s the way it goes,” Woods said.
“That round was easily six, seven-under par. It turned into even par which is not what I needed to do.”
Woods has joined fellow Nike-sponsored athletes in defending Colin Kaepernick after the former San Francisco 49ers quarterback became new face of the brand’s ‘Just Do It’ campaign.
Kaepernick drew controversy for kneeling during the US national anthem prior to NFL games but Woods has backed Nike’s decision to run with the campaign.
“I think Nike is trying to get out ahead of it and trying to do something special and I think they’ve done that,” said the 14-time Major winner.
“It’s a beautiful spot and pretty powerful people in the spot.”
