Impact head to Columbus short at left back

The Montreal Impact will have to improvise at the left back position with Ambroise Oyongo and Daniel Lovitz both out with knee injuries.
Right back Chris Duvall will move over to the left side for a game Saturday at Columbus, but Duvall and midfielder Marco Donadel will sit out the second leg of the hotly disputed Canadian Championship final in Toronto three days later with one-game suspensions for yellow card accumulation.
Who will play on the left side in that match is anyone’s guess.
