Just as D.C. United was beginning to regain its health, the injury bug struck again.

Midfielder Chris Pontius (concussion) and defenders Ethan White (hip flexor) and James Riley (adductor) will miss Saturday’s match against Toronto FC at RFK Stadium after suffering setbacks in Wednesday’s U.S. Open Cup game, the club announced. Defender Dejan Jakovic (adductor) and midfielder Kyle Porter (calf) are listed as questionable.

Pontius, White and Riley started in the 3-1 victory over the Philadelphia Union at Maryland SoccerPlex. Pontius did not return for the second half. The others departed midway through the half. Jakovic and Porter did not play.

Coach Ben Olsen is expected to provide details about the injuries and the long-term outlook after training Friday.
