Tiger Woods has withdrawn from the Northern Trust, he announced Friday.
"Due to a mild oblique strain that led to pain and stiffness, I have to withdraws from the Northern Trust," Woods said in a statement Friday. "I went for treatment early Friday morning, but unfortunately I'm still unable to compete."
Woods made numerous mistakes Thursday on his way to shooting a 4-over-par 75 at Liberty National in the first round of the Northern Trust.
"I just didn't play well," Woods said Thursday after finishing the round tied for 116th out of 120 golfers.
