Union coach Jim Curtin revealed Blake had suffered a groin tear on Wednesday. Curtin declined to give a timetable for Blake's return though he hopes the absence won't be a long one.
Blake picked up the injury during last weekend's 3-0 win over the Montreal Impact, and was forced to exit in the second half.
Meanwhile, Fabian has returned to the training pitch in a limited capacity following an ankle sprain sustained during an April 13 loss to the LA Galaxy, Curtin said.
