Fitzpatrick agreed to a professional tryout agreement with the Panthers ahead of training camp, per CapFriendly.
Selected by the Blues in the second round of the 2016 NHL Draft, Fitzpatrick has yet to make his NHL debut. With both Sergei Bobrovsky and Spencer Knight under contract for the upcoming season, Fitzpatrick's best hope will be to earn a two-way deal that will see him primarily playing in the minors.
