According to Chris Johnston Gus Nyquist may be out for the rest of the season, as he will require surgery on his injured shoulder, but they haven't ruled out a possible return for the final two weeks of the season if possible.
This is a cautionary tale of keeping talent as a trade chip for too long, and this isn't the first time a General Manager has fumbled a chance at trading for assets. Nyquist will recover and hopefully, will return healthy and return to play soon. Nyquist's contract is ultimately affordable and team-friendly for someone of his caliber.
But this is a cautionary tale that NHL General Managers have to be aware of. Multiple reports now state that teams are interested in moving their top trade pieces sooner rather than later. Early this season the Canucks had an injury scare involving Bo Horvat, and that was one of the reasons they opted to make a move so soon.
