‘The play-making forward registered an assist in one preseason game, but had been bothered by a sore back for most of the past week. He missed 34 games last season, including the final 12, after having surgery to remove bone chips from his hip. And Connolly has appeared in only 50 games over the past two seasons as a result of injuries.’
