That is, a discussion of Neil Walker's back, which is not quite the same thing as Walker is back. A "herniated disc" is the first opinion although, as always, a second will follow. Alderson calls it a "pretty routine" disc injury that is causing weakness is Walker's lower body, "but not significant enough to prevent him from playing". He goes on to dismiss rumors that it could be a career ending situation as "fabrication"; "I don't want people to become too concerned about where we are. I don't think it's as serious as it's been portrayed." sez Sandy. So, unless the second opinion proves more dire than the first by warning of further damage if he plays with his present condition, this is basically a pain management issue and Walker could be back in the lineup later this week if and when he feels up to it. http://m.mlb.com/news/article/198735808/neil-walker-should-be-ok-to-return-in-2016/
