Blues forwards David Backes and Robby Fabbri left Game 4 with injuries and did not skate Monday morning. Blues coach Ken Hitchcock indicated each will warm up and be game-time decisions. Will they play? If they do, how effective will they be?

Fabbri leads the Blues with 14 points (3 goals, 11 assists) in the Stanley Cup Playoffs. Backes is tied with Vladimir Tarasenko and Troy Brouwer for first on the Blues with seven goals and is tied with Tarasenko and Jaden Schwartz for second with 13 points.
