The Union, who have used a break from MLS competition lately to advance to the U.S. Open Cup quarterfinals, resume league play today when D.C. United visits PPL Park for a 7 p.m. kickoff.

Here's the updated injury report for the Union, who are searching for their first league victory since April 21:

OUT: FW Krystian Witkowski (concussion symptoms)

QUESTIONABLE: MF Cristhian Hernandez (R knee sprain); MF Gabriel Gomez (L knee contusion); FW Lionard Pajoy (L calf contusion)

PROBABLE: DF Gabriel Farfan (lower back muscle spasms); MF Michael Farfan (L foot strain); DF Sheanon Williams (R big toe sprain); GK Chase Harrison (L ankle sprain); MF Keon Daniel (L ankle sprain); FW Freddy Adu (L calf strain)

What we can glean from the injury report is the Union are thin on the defensive front. If the Farfan brothers and Williams are unable to play, the Union will be looking to Ray Gaddis and Carlos Valdes to hold down the fort, with Amobi Okugo also getting a look at centerback.
