Seamus Power and Rory McIlroy will also be in action later this afternoon
Tiger Woods returns to action in the Genesis Invitational on the PGA Tour in California today.
It's a tournament Woods has never won - he tees off at 5:25pm Irish time.
Just after 4:30pm, Seamus Power begins his challenge, and Rory Mcllroy - who will become the new world number one if he wins this week - is out just before 8 o'clock Irish time.
Woods only played three tournaments last year as he underwent ankle surgery.
