Mike Knuble will draw back into Washington's lineup in Game 4 on Thursday night for the first time since Apr. 5. It will mark his 2012 playoff debut after sitting in the press box for the previous three games of the Capitals' opening round series versus Boston. Knuble is set to join the fourth line with Keith Aucoin and Joel Ward. He posted just six goals and 12 assists in 72 games for Washington during the regular season.
