The date when Tiger Woods makes his expected return to official U.S. PGA Tour action remains a closely guarded secret, but we now know at least one key aspect of that comeback.

Just before Christmas, Woods – who turns 42 on 30 December – announced via Twitter that he would no longer be working with his swing coach since November 2015, Chris Como.

He wrote: “Since my fusion surgery I have been working hard to relearn my own body and golf swing. I’ve done this by primarily relying on my feel and previous years of hard work with Chris. For now, I think it’s best for me to continue to do this on my own. I’m grateful to Chris Como for his past work, and I have nothing but respect for him.”

Woods has had three previous swing coaches on the U.S. PGA Tour: he won eight of his 14 majors with Butch Harmon between 1996 and 2003 and six more with Hank Haney over the following six years; then spent four years with Sean Foley up to 2014.

His last worldwide win was the 2013 WGC-Bridgestone Invitational, before health (and other) issues stalled his progress.
