CLEVELAND (AP) — Forward Clint Dempsey, midfielder Michael Bradley and goalkeeper Tim Howard are among six additions to the U.S. roster for the knockout phase of the CONCACAF Gold Cup.

U.S. coach Bruce Arena also added forward Jozy Altidore, midfielder Darlington Nagbe and goalkeeper Jesse Gonzalez, the U.S. Soccer Federation said Sunday. Gonzalez’s application to change affiliation from Mexico to the U.S. was approved by FIFA last month, after the deadline for setting the 23-man roster for the group phase.

Goalkeepers Brad Guzan and Sean Johnson were dropped along with midfielders Alejandro Bedoya, Cristian Roldan and Kelyn Rowe, and forward Dom Dwyer. Arena had planned in advance to replace Guzan, Johnson and Bedoya.

Bedoya is expecting the birth of his second child next week.

The U.S. plays its quarterfinal Wednesday in Philadelphia against a third-place team from another group, likely Honduras, El Salvador or Jamaica.
