It seems to have been there, more often than not, for years. If it's not a HDMI port that plugs him into a computer at night then maybe it really is a plaster. Perhaps covering up the wounds sustained when he used to wear those huge watches pre-2008. (I always wondered why a pro athlete needed to wear a watch on court. Did he think the service judge would filch it if he left it in his bag?) Surely there are BC'ers who know the real answer.
Always wondered about that too. IIRC he had also worn a Phiten power band there in the past, so maybe this is the replacement...
if i am not mistaken, somebody did ask LCW before during an interview. He did replied that it was just a normal plaster but its for good luck charm. He did also mentioned that Taufik Hidayat has the same plaster and he asked what is it for, Taufik told him that its just a lucky charm. LCW tried it and he won that tournament. Later it became a habit for him to have that band aid on his left wrist.
Thank you for that answer. A lucky charm is so much nicer an explanation than some health problem. Thank you. So is Finland. http://depressingfinland.tumblr.com/post/69893425717/meanwhile-in-finland
it is a lucky charm. LCW said some years back, he won the the game while the plaster on his wrist. since that day, he will apply the plaster on his wrist as a lucky charm
