D.C. United midfielder Branko Boskovic will not play Friday night against the Houston Dynamo at Robertson Stadium (8:30 p.m. ET, Fox Soccer Channel), the club announced. He suffered a knee contusion late in the U.S. Open Cup match Tuesday, and despite an MRI exam showing no damage, he was scratched from the travel roster and will prepare for a pair of league games next week.

Midfielder Kurt Morsink (concussion) is also out, but defender Jed Zayner, sidelined since the season opener with a hamstring injury, and goalkeeper Steve Cronin (wrist) are available.

With Cronin on the active roster for the first time, backing up Bill Hamid, Pat Onstad will not be in uniform and turn his full attention to his assistant coaching duties. Onstad is the subject of my print/online story today.

Game-time weather forecast in Houston: 77 degrees and clear.
