American golfer Tiger Woods on Friday decided to withdraw from the second round of the Omega Dubai Desert Classic due to back pain.

“Tiger Woods went into a spasm in his lower back fairly late last night. He says it’s not the nerve but back spasm, and he can’t get the spasms to calm down,” said his agent, Mark Steinberg, reports Efe.

Woods has won 79 golf tournaments in his career, including 14 Grand Slams. His last was the US Open in 2008.

Tiger has pulled out of 7 tournaments since 2010 and had 4 withdrawals.

“I wasn’t in pain at all … I was just trying to hit shots and I wasn’t doing a very good job,” Woods said after his opening round.

Earlier, Woods made a comeback after a 16-month layoff caused by multiple back surgeries.

When it comes to his form, the 41-year is struggling horribly as he now puts his future in doubt after withdrawing from the Desert Classic.
