I believe that he is done for the year. His shoulder isn't healing as fast as expected. I would have loved to see him play the full year in Hartford to see what he is made of and get him ready for the season after the NHL comes back
Original prognosis was he'd be back for February. I really haven't seen any updates but according to Bridget Wentworth of the star ledger, it sounds as if he's likely out for the year.
Actually I happened to meet Jim Schoenfeld at the recent AC Bullies vs Charlotte Checkers ECHL game and they believe he's most likely done for the season. He'll be reevaluated in March and has made some but not much improvement as noted in the article #37-#93-#27 references.
