Fasching suffered a groin injury in Sunday's game against the Jets and will not return, Paul Hamilton of WGR Sports Radio 550 reports.

Fasching hasn't made much of an impact in six NHL games this season (Sunday included), failing to tally a point yet this season. He had seen increased ice time and carved out a role on the man advantage, but will now have to wait until at least Tuesday when the Sabres travel to Minnesota to rejoin the lineup.
