Aweek after his son T.J. underwent open-heart surgery, Panthers tight end Greg Olsen was back at work Monday.After practice, Olsen gave an update on T.J.’s condition, saying the soon-to-be two-year-old is still in ICU, but doing well. It’s unclear when he’ll be able to go home.T.J. was born with hypoplastic left heart syndrome, a severe congenital heart defect. Last week’s procedure was his third and final surgery in an exhausting physical and emotional process that may finally be coming to an end.”We’re very fortunate and blessed that he’s responded how he has. We just have to hope to keep him on this track, and if that’s the case, we should be in pretty good shape,” Olsen said.”It’s been a long two years of preparing for this, and we’re pretty excited that hopefully it’s almost over.”
