*D.C. United’s Dwayne De Rosario returned to regular training Thursday after resting a sore shoulder injured in the first half of last weekend’s 1-0 victory over the Columbus Crew. Coach Ben Olsen said he expects the 2011 MLS MVP to play Saturday night at Sporting Kansas City (8:30 p.m. ET, Comcast SportsNet).

*Defender Mike Chabala, acquired from the Portland Timbers on Thursday, was scheduled to practice Friday morning and travel with the club to K.C. in the afternoon.

*Midfielder Andy Najar had a good week of practice since returning from the Olympics, Olsen said.

“I talked to Andy to make sure he understands it’s D.C. United time, come back here and make sure your focus is here now, put [the Olympics] behind you and take care of your job. He looks like he is happy to be back with the guys and back home. ... The guys are happy to see him. He is everybody’s little brother and they were proud of him but they’re ready for him to fight for us now.”

*Defender Ethan White has yet to crack the regular roster since recovering from knee surgery in March, but he has benefitted immensely from periodic loans to the third-division Richmond Kickers — a preferrable arrangement to MLS reserve matches.

“It’s probably the best way to go about our reserves that aren’t playing a lot of minutes in the future,” Olsen said. “Putting them in these real games and putting them through these real seasons. ... That’s how you grow, when you are part of a team and you have to make the playoffs and you have to go to an away game and [for example] grind out on a small turf field. Those are all growing experiences for some of these guys. The reserve games, sometimes you don’t get that energy or commitment from every guy.”

Defender Conor Shanosky has been on a season-long loan to the second-division Fort Lauderdale Strikers and goalkeeper Andrew Dykstra has made regular appearances with the third-tier Charleston Battery.

*Right back Robbie Russell had the protective boot removed from his injured left foot Wednesday and was working out on a stationary bike Thursday. A specific timetable for a return to active duty hasn’t been set.

Speaking of Russell, he will make introductory remarks at a reading given by Gwendolyn Oxenham, a fellow Duke grad who wrote a highly acclaimed book, “Finding the Game: Three Years, Twenty-five Countries, and the Search for Pickup Soccer.”

The event will take place next Thursday at Stoney’s Bar and Grill at 1433 P Street NW. Signed copies will be available for $20, with $5 of every purchase going to United Reads, a DCU program promoting reading in local communities.

Doors open at 5:15 and the event starts at 6. Afterward, Oxenham, a former Duke star, will lead a pick-up game at Stead Rec Center at 17th and P streets.
