OTTAWA -- St. Louis Blues captain David Backes left the game against the Ottawa Senators on Monday during the second period with an upper-body injury.
Backes skated slowly off the ice and went to the dressing room with 2:49 left in the second after he collided with Ottawa's Colin Greening on an open-ice hit. He did not return.
Backes had seven hits and won 71 percent of faceoffs in 11:20 in ice time before he left the game. He has 16 goals and 14 assists this season, second on the team behind linemate Alexander Steen (35) in points.
Ottawa won the game in overtime, 3-2.
