*D.C. United will not offer contracts to American defender Frankie Simek and English forward Akpo Sodje, Coach Ben Olsen said Friday. Both had been on trial this week.

With the European seasons ending, several trialists will pass through Washington in the coming weeks.

“At this point, to sign someone, they’ve got to be the right guy because summer is coming up and a lot will come our way,” Olsen said. “We obviously want to make additions, so I don’t want to do anything that isn’t a good move for the future.”

*Injury update: Midfielder Chris Pontius, out for three matches with a groin ailment, is optimistic he will be available Sunday against Sporting Kansas City at RFK Stadium.

“It’s the best I felt since the injury happened,” he said.

Said Olsen: “He has had a good week.”

*After playing 45 minutes last weekend, midfielder Nick DeLeon should be able to go for a longer stretch Sunday in his continuing progress from a long-term hamstring injury.

“They’ll both factor in the game,” Olsen said of Pontius and DeLeon.

*Midfielder Marcelo Saragosa is out four to six weeks after undergoing knee surgery this week. Forward Carlos Ruiz (ankle) is questionable and did not practice today. Midfielder John Thorrington (knee) is questionable but has resumed workouts after a two-month absence and is working on match fitness. Midfielder Lewis Neal (groin) remains sidelined and might need additional surgery.

*Goalkeeper Andrew Dykstra and homegrown forward Michael Seaton reported to Richmond for the USL match tonight between the Kickers (4-0-2) and Los Angeles Blues (4-4-1).

The others in the loan agreement — forward Casey Townsend, defender-midfielder Taylor Kemp and defender Conor Shanosky — remained in Washington. Perhaps a clue as to which players will compete for Richmond in the U.S. Open Cup? The Kickers will host amateur Icon FC on Tuesday in the second round. A player cannot compete for multiple teams in cup competition, even if one club is eliminated.

If the Kickers advance, they would host United on May 28 at City Stadium. United General Manager Dave Kasper was nearing a decision about cup assignments.

*How does the Open Cup hosting process work? Jeff Crandall witnessed the third-round draw in Chicago and offers this insight.

*TV on Sunday: Comcast SportsNet, Univision Deportes, 5 p.m. ET.

*Referee: Jair Marrufo.

*Sunday weather outlook: 70 degrees, scattered thunderstorms.
