Columbus Crew SC midfielders Ethan Finlay and Tony Tchani will be invited to United States training camp for the first time later this month, according to an MLSsoccer.com report.
The Crew's Wil Trapp will also return to camp after earning his first cap last January, the report said.
Finlay, 25, scored a career-high 12 goals with 13 assists last season, one of just four MLS players in double figures in both categories.
Tchani, 26, declined a call-up from his birth country of Cameroon in November because of an injury. He became a U.S. citizen in 2013.
Jurgen Klinsmann has said he would use the January camp in Carson, Calif., to prepare both the senior team for upcoming World Cup qualifiers against Guatemala, as well as the Trapp's under-23 side for their Olympic playoff against Colombia.
The U.S. will face Iceland in the first friendly 2016 on Jan. 31 before hosting Canada on Feb. 5. They do not fall on FIFA fixture dates, so European-based players are unlikely to join the camp.
