Erat substitute

Sustaining an upper-body (hand/arm) injury in Wednesday's 4-3 loss to the New York Rangers, Washington Capitals forward Martin Erat may be on the shelf for Game 5 and beyond. If so, Katie Carrera of The Washington Post suggests Capitals coach Adam Oates may look beyond his reserve of NHL healthy scratches -- Aaron Volpatti and Wojtek Wolski -- as substitute for Erat.
