*Goalkeeper Bill Hamid and midfielder Perry Kitchen arrived at D.C. United training camp in Charleston, S.C., and seem likely to play in the Carolina Challenge Cup finale Saturday against the Columbus Crew (5 p.m., live video at dcunited.com). Both served U.S. under-23 national team duty in Dallas for 10 days.

*Guilherme, a Brazilian left back on trial for two weeks, was released. The club liked his athletic qualities but concluded he was too raw to claim a roster spot. Had United added him, he would’ve been on a year-long loan from Botafogo.

Will Guilherme’s departure prompt United to sign veteran left back Jose Burciaga Jr.? He was listed as a “guest player” at the Arizona phase of camp but then accompanied the team to Charleston. He started Wednesday against the Battery and set up Ryan Richter’s goal. Burciaga, 30, hasn’t played in MLS since 2008 with the Colorado Rapids. Between 2001 and ‘07, he made 115 appearances for the Kansas City Wizards.

Daniel Woolard is the first-choice left back, with second-year Chris Korb as an option.

The other remaining trialists: midfielders Lance Rozeboom (New Mexico) and Seth C’deBaca (Georgetown) and defender-midfielder-forward Richter (formerly with the Philadelphia Union).

UPDATE 4:17 P.M. SATURDAY: C’deBaca has been released.

*As expected, Conor Shanosky, a second-year homegrown midfielder from Sterling, Va., will go on a season-long loan to the second-division Fort Lauderdale Strikers.

“This is a great opportunity for Conor to continue his development,” United General Manager Dave Kasper said. “The loan will allow him to get important first-team experience on a regular basis.”

Shanosky, 20, played in seven reserve matches last year and appeared in the friendly against Dutch club Ajax.

*The club will return to Washington on Sunday to begin final preparations for next Saturday’s MLS opener against Sporting Kansas City at RFK Stadium (7:30 p.m., Comcast SportsNet Plus). The 10th annual kickoff luncheon, benefitting the club’s charitable arm, United for D.C., will be held Monday at the Washington Marriott Wardman Park.

*Kenny Arena, son of former United coach Bruce Arena and a DCU reserve midfielder in 2005, was named head coach at Florida International University. Arena, 31, was an assistant at Virginia (his alma mater) in 2006, George Mason in 2007 and UCLA the past four years.
