Girgensons (upper body) will not play in Monday's contest against Detroit, per Bill Hoppe of the Olean Times Herald on Sunday.
Girgensons will remain sidelined for the Sabres' second-consecutive contest against Detroit. The 28-year-old has averaged 15:22 of ice time -- 1:36 during the power play -- and has recorded 12 points over 33 appearances this season. He is questionable for Tuesday's game against Ottawa.
