Experts striking cautionary note on Tiger's resurgence

As anticipation builds over Tiger Woods' official comeback after nearly a year rehabilitating from a spinal fusion, two former professionals have offered a tempered view of what to expect from the 14-time major champion in 2018.

Woods completed 72 holes for the first time in three years when he finished tied for ninth in a field of 18 at the Hero World Challenge in the Bahamas in December - an unofficial event on the PGA Tour.

That was an appetizer before he continues his return at this week's Farmers Insurance Open at Torrey Pines in southern California.
