Tiger Woods on his mother: "Meant everything"

A "rock". That's how Tiger Woods describes his mother Kultida Woods, who passed away on February 4, in an interview with CBS late on Sunday.

She meant everything to me and losing her has been a very tough and difficult process to go through, says Woods.

The 49-year-old golf star was supposed to play the tournament at Torrey Pines in San Diego, California – which he hosts – but withdrew after his mother's passing.
