D.C. United find themselves shorthanded at the fullback position after suffering three injuries to starters in a four-day period.
Left back Chris McCann pulled up lame in the second half of Tuesday's 0-0 home draw vs. Montreal with a hamstring problem, and in the game's final moments was joined on the sidelines by right back Leonardo Jara.
McCann was appearing in relief of Joseph Mora, who sustained a concussion and broken jaw in the 2-1 win over Orlando City on March 31. The Black-and-Red are already missing Oniel Fisher due to a long-term knee injury, while Chris Odoi-Atsem's availability for match action is unclear in the wake of his successful battle against Hodgkin's lymphoma.
Reserve defender Jalen Robinson can play both center back and fullback; he was Jara's replacement in the dying minutes on Tuesday. Rookie Akeem Ward is also an option; primarily a right back, he has yet to make his MLS debut. Both are predominantly right-footed.
