Apparently Ty Smilanic has left Wisconsin and is pursuing a pro deal with Montreal.
"One name fans might be surprised to see on the list is Ty Smilanic, acquired from Florida in February as part of the Ben Chiarot trade. After spending the past two seasons as a member of the men's hockey team at Quinnipiac University (NCAA), Smilanic transferred to Wisconsin in May.
NCAA players are not permitted to participate in fall NHL camps, but according to a report by Radio-Canada's Marc Antoine Godin, the young forward "has decided to leave Wisconsin and will attend rookie camp (and hopefully the main camp) with the hopes of landing a pro contract."
