Anderson is considered day-to-day with an upper-body injury, Lance Lysowski of The Buffalo News reports.
Anderson has been missing from some practices of late for maintenance purposes. He has posted a 10-11-2 record this season with a 3.07 GAA and a .908 save percentage in 25 appearances. The Sabres still have healthy goaltenders Eric Comrie, Ukko-Pekka Luukkonen and Devon Levi on the roster.
