Woods has skipped the first five events of the 2003 season due to knee surgery he had on Dec. 12.
'Things are progressing nicely and I will officially enter the Buick Invitational on Thursday,' he said. 'I'm starting to get accustomed to having full practices and I'm excited about working on my game again.'
Woods, who is sponsored by Buick, won this event in 1999.
Woods also responded to criticism by Phil Mickelson, who said the worlds No. 1 player was using inferior equipment.
'I heard it was said in fun and jest, but until I talk to him, I really don't know,' Woods said. 'When I find out, I'll get a better perspective.
'Phil is entitled to his own opinion, but as everyone knows, I don't switch equipment until I find something as good or better than what I have been playing with, and my Nike products are just that. I've said it time and time again.'
Woods has endorsed Nike since joining the PGA Tour in 1996. He switched from Titleist clubs to a Nike driver and irons last year. He has won six majors with the Nike ball, two of which came with the Nike driver.
'Quite frankly, questioning my equipment is foolish,' he said. 'I'm not going to play with anything that is going to hold me back. ... Nike Golf has given me the best possible equipment.'
Woods has not played in a competitive event since his Target World Challenge in early December. On Tuesday, he played 18 holes for the first time since his surgery.
'I played with my dad and he hit it pretty darn good for age 70,' Woods said. 'I was pleased with the way I hit it, too. I shot 66, which isn't too bad.'
