Tiger Woods practices today at Firestone Country Club (Mark Duncan / AP)

He was no longer limping, apparently sufficiently recovered from the knee injury that has sidelined him since May. He had a new caddie by his side. He had no gallery for his Bridgestone Invitational nine-hole practice round, only a grounds crew and a few reporters. He was downright chatty, inquiring about a reporter’s knee replacement. The reporter told him that it set off TSA alarms at airports but was otherwise fine.

“The screw in my knee sets off the alarms at security when I go through,” Woods said, via Larry Dorman of the New York Times.

Gasp. Tiger Woods on a commercial airline? We’re probably not talking middle seat, but still ... the relevation was shocking.

“Sometimes on the longer hauls,” he said

As for golf, his tee shot flew into the light rough left of the fairway. He and his swing coach, Sean Foley, and his new caddie, long-time friend Bryon Bell, took off after it. Back to work for Tiger Woods.
