I am sad aboutCarlos, but not surprised (and actuallythink it's a sensible move). I was reading an artcle about players with wrist injuries - most famouslyDel Po.- and how his injury really de-railed what was a career that was on course to really the big 3. Rafa's 'come back' in 2016 (after a drop in form in mid 20 14/ through 2015) was thrown off by a wrist injury.
Domi Thiem's career never recovered from surgery.
I hope for Carlos's sake, it's not so serious.
