Bertuzzi recently underwent a procedure on his knee, Dhiren Mahiban of The Canadian Press reports.The 39-year-old Bertuzzi had been pursuing a return to the NHL this season, only to see his plans thwarted when he developed the knee issue while skating with AHL Binghamton on a professional tryout offer. It's unclear how long of a recovery timetable Bertuzzi will face following the procedure, but regardless, it seems likely that the winger could just decide to call it a career.
