Gilbert (upper body) will return to the lineup for Wednesday's postseason opener against the Senators, John Lu of TSN reports.With Gilbert now healthy after missing the Canadiens' last two regular-season contests, Sergei Gonchar, Greg Pateryn, and Mike Weaver will head to the press box to serve as the healthy scratches on defense. The 32-year-old Gilbert had a rough first season in Montreal, seeing his scoring total drop 16 points from the total of 28 he posted with the Panthers in 2013-14.
