Tiger Woods was sporting a “cool daddy-o” beard when he met the press Tuesday at Aronimink Golf Club in Philadelphia ahead of his AT&T National tournament. That wasn’t the only thing that was different about him: he had no walking boot and wasn’t limping. Still, he said there is no timetable for his return to the sport he formerly owned

“Usually I set a timetable when I want to come back and play, when I’ve had injuries before,” Woods, who missed the U.S. Open because of knee and Achilles injuries, said. “This one is different. I’m just going to learn my lesson … and apply it this time and come back when I’m100 percent. I don’t know when that is going to be.”

Woods initially was injured at the Masters and, save for nine holes of golf at the Players Championship, he has not played competitively since. He refused to rule himself out of the July 14-17 British Open but said he wants to be fully healthy in order to play.

“I’m progressing,” Woods said. “If I had knee surgery and I was out for a while, then it’s a different deal. I haven’t gone under the knife. I’m strengthening and trying to get this thing stronger and explosive again.”
