McIlrath exited Saturday's preseason game against the Columbus Blue Jackets due to a lower-body injury and was absent from practice on Monday. The extent of his injury is unclear, but he was likely a long shot to make Washington's opening night roster on Thursday against the Boston Bruins. That said, the 33-year-old McIlrath was a solid depth blueliner for the Capitals last season, tallying two points (0G / 2A) in 17 games.
