Commesso was assigned to AHL Rockford on Sunday, Charlie Roumeliotis of NBC Sports Chicago reports.
Commesso wasn't particularly effective during his lone preseason start, as he turned aside 35 of 42 shots in a 7-2 loss to Minnesota. He made 38 regular-season appearances for Rockford last year and will return to the minors now that the preseason has concluded. Since Laurent Brossoit (knee) will begin the season on injured reserve, Commesso could be called up if Petr Mrazek or Arvid Soderblom deal with injuries at some point.
