The 31-year-old goaltender is just 11-13-2 this season with 3.12 goals-against-average and a .898 save percentage.
The Sabres, who started the year with high Stanley Cup aspirations, added high-priced players Ville Leino, Christian Ehrhoff and Robyn Regehr in the summer, but have been hit hard by injuries.
The team currently sits in 11th place in the Eastern Conference, and nine points out of a playoff spot.
Following Monday's 5-0 loss to the Detroit Red Wings in which Miller was pulled, the veteran goalie dismissed the idea that making a significant trade would help the Sabres turn their season around.
