Liverpool confirmed this afternoon that Lucas had successfully undergone surgery in Brazil on the Anterior Cruciate Ligament injury he sustained at Chelsea last week. LFC medical staff were present during the procedure. Lucas will now begin an agreed rehabilitation programme which will be overseen by the Club's medical team. http://www.liverpoolfc.tv/news/latest-news/lucas-operation-a-success
Step one complete - we won't know if the procedure is a success for several months and the rehab is listed as 6-12 months. Preseason might be a good target, if somewhat ambitious...
He probably felt comfortable with someone down there and to be around family right after it was done.
