With Hamid’s return, Travis Worra would yield a starting role that he has filled admirably for 11 consecutive matches. A second-year pro who made one MLS appearance last year, Worra has recorded four shutouts and conceded 10 goals. Along the way, he has grown in confidence and made several high-quality saves.

Hamid, United’s first-choice keeper for five years, missed not only the first third of the MLS season, but also the CONCACAF Champions League quarterfinals, U.S. national team winter camp and World Cup qualifiers, as well as consideration for Jurgen Klinsmann’s Copa America Centenario squad.

For now, Worra will back up Hamid. Long term, United would like him to remain active. That would require a loan to a second- or third-tier club. Last week, United’s Charlie Horton was assigned to United’s USL affiliates, the Richmond Kickers.

“Our challenge now is to figure how to keep him sharp and give him a season,” Olsen said of Worra. “He’ll continue to compete for the [starting] spot but also we have to figure out ways to getting him games because he has proven to us over the last two months that he is a guy who can play in this league. It’s up to us to make sure he’s in the right developmental plan and foster him throughout the next year to get him to where he needs to be.”

Tally Hall, Worra’s back-up for two months, and Andrew Dykstra, who started the league opener before undergoing back surgery, are the other goalkeepers on the roster.

Attacker Chris Rolfe remains sidelined with a concussion suffered April 30 at Chicago. He will miss the Kansas City match and Seattle’s visit to RFK Stadium next Wednesday, which takes him into the Copa America break. United is off until June 15 for the U.S. Open Cup’s fourth round against the third-tier Richmond Kickers or second-flight Fort Lauderdale Strikers.

“He is taking some small steps,” Olsen said. Rolfe has not been cleared to practice and, for the most part, has remained away from the team. He did visit the group at RFK on Wednesday. …

Forward Alhaji Kamara, who signed two weeks ago, will travel with the squad to Kansas City and might play a few minutes as he builds his fitness after a long layoff, Olsen said.

“We have a plan for him in place, and that’s getting him some time in games but pushing him along daily to get his lungs bigger,” Olsen said. “A few minutes wouldn’t hurt him.”

Kamara has chosen to wear No. 45. Why such a high number? The “9” was not available, so he selected two digits that add up to it. …

With Steve Birnbaum on U.S. national team duty, Kofi Opare is expected to join captain Bobby Boswell in central defense. Forward Alvaro Saborio joined the Costa Rican squad, opening space for Fabian Espindola to rejoin the starting lineup. Midfielder Markus Halsti, who has yet to play this season, flew to Finland ahead of friendlies against Belgium and Italy. …

Midfielder Paul Clowes, whom United released when Kamara signed, has joined USL’s Charlotte Independence.
