Tiger Woods will be concentrating on hosting duties instead of competing at the Genesis Invitational as he recovers from his fifth back operation.

And the 15-time major winner will be paying special attention to the exploits of a 32-year-old mini-tour veteran making just the second PGA Tour appearance of his career at Riviera Country Club.
