After opening its four-game road trip with a tough 2-1 shootout win in Minnesota, the Florida Panthers (27-23-6) will face the St. Louis Blues (24-25-3) tonight at Enterprise Center. The Cats will be looking to avenge a 5-4 overtime loss to the Blues at FLA Live Arena on November 26. St. Louis had lost five straight before Ryan O’Reilly’s overtime goal gave them a 6-5 win over Arizona in the opener of a four-game homestand on Saturday. Spencer Knight is expected to start. It will be his first NHL action since January 8. when he lost to the Dallas Stars.
