The deal is for two years, and while the amount of money hasn't been confirmed by anyone as of this writing, it's not likely for much money. The first year of the deal is a two-way deal, which means the Wild will be able to send him to the Iowa Wild (AHL) without paying him an NHL salary, while the second year will be a one-way deal, meaning that if the Wild sent him to Iowa, they'd have to pay him an NHL salary.
Though as we saw last season, injuries happen. When they inevitably do next year, Zucker ought to be on the short-list of call-ups. Zucker will get another shot with the Wild. What he does with it is up to him.
