Funk, 52, opened The Players Championship with a 73.
After having his troublesome right knee drained countless times after knee surgery a year ago, he contracted a staph infection in December that's required a series of surgeries to correct. Funk played Thursday in a knee brace in just his third PGA Tour start this season.
'I'm just hitting it so short right now, not that I was ever long,' Funk said. 'I can't hit it out of my shadow.'
Funk said doctors have told him he must wait six months, because of the infection, to be eligible for a knee replacement, something he's seriously considering doing in October if he doesn't feel better. Still, he plans to play up to 20 events over the next 25 weeks, most of them Champions Tour events, if his knee holds up. His exemption into The Players Championship as the 2005 champ ends after next year's event.
