Eichel, who has an upper-body injury, was a full participant in the morning skate. The announcement was made about 10 minutes before puck drop.
"It was something that evolved in the warmups so we'll just look at the situation and get back to you tomorrow on that," Sabres coach Ralph Krueger said.
Eichel could have matched the Buffalo record of 18 straight games with a point, set by Gilbert Perreault (Oct. 24-Dec. 4, 1971).
Eichel had 31 points (16 goals, 15 assists) during his streak, which was the longest in the NHL this season and tied Dave Andreychuk for second-longest in Sabres history. Andreychuk had two 17-game point streaks (Dec. 31, 1991-Feb. 4, 1992, Oct. 18-Nov. 14, 1992).
Sabres forwards Johan Larsson and Evan Rodrigues were injured during the game.
Larsson sustained an upper-body injury 3:12 into the second period, and Rodrigues sustained a lower-body injury 3:08 into the third period when he was hit in the left leg by a shot.
Krueger said they were being evaluated.
