Per Katie Carrera, Patrick Wey will make his NHL debut tonight (and be the 12th blueliner the Caps have used already this season) in front of Braden Holtby in net, so expect the following line combinations and defensive pairings:
Marcus Johansson - Nicklas Backstrom - Alex Ovechkin
Eric Fehr - Mikhail Grabovski - Troy Brouwer
Jason Chimera - Martin Erat - Joel Ward
Aaron Volpatti - Jay Beagle - Tom Wilson
Karl Alzner - Mike Green
That leaves Steve Oleksy and Alexander Urbom as healthy scratches, Brooks Laich, John Erskine and Jack Hillen out with injury, and Philipp Grubauer backing up in net.
