Bit of a Culkin update: Looks like he's doing well and now has the cast/brace off from the surgery. He seemed more concerned about his hand modelling career then playing career. He was also showing off the scar from the cut and surgery. It was a fairly significant cut that he suffered and seeing the scar, he was very lucky.
(Behind tags, but it isn't that bad. It's a clean scar, no blood or guts or insanely grotesque deformity)
