Tiger Gets Thumbs-Down...What's The Story?

I was unable to watch the Quail Hollow telecast, but I couldn't help but notice this photo with Steve Elling's account of the round.

Were they commenting on his round or something else?

Doug Ferguson's AP story explains:

This was Woods' first time playing at a regular PGA Tour event with public ticket sales, and the crowd was gracious as ever with a few exceptions. Two fans, including a woman, held thumbs-down as Woods walked off the 15th green. Police also escorted away a fan who apparently heckled Woods as he left the 17th green. A friend of the fan, who declined to give his name, said the fan only said, "No red shirt for you on Sunday."
