It’s been a difficult year for Tiger Woods, who withdrew from the Arnold Palmer Invitational at Bay Hill on Tuesday because of back problems and the host of that tournament believes the injury doesn’t bode well for Woods.

“I don’t think 38 years is the ultimate stopping point for his quest to do what Jack did,” Palmer said of Woods’s pursuit of Jack Nicklaus record 18 major titles in a session with reporters. Woods, whose last major win was at the 2008 U.S. Open, has 14. “I think it lessens the possibility of that happening. It’s going to be tough. It’s going to be tough to keep the concentration and the type of game that is necessary to win majors.

“Add in the fact that [the depth of talent is] tough. And they’re strong. … And the fear of a player being so good that they back off, I don’t think that’s the case anymore. I think that the players that are going to win and win major championships have to be physically fit and mentally fit.”

Woods, who has played few rounds this year and was withdrew from the Honda Classic on March 2 and struggled in the WGC Cadillac Championship, wrote on his website that back spasms and pain haven’t subsided and that, at this point, “it’s too early to know about the Masters.” Woods is receiving treatment and resting up for the April 10 Masters.
