CARSON, Calif. – Bradford Jamieson IV is back in the fold with the LA Galaxy after a successful stint with the U.S. U-20’s at the 2015 FIFA U-20 World Cup, but the youngster has yet to return to the field.

Jamieson scored a goal and made four appearances at the U-20 World Cup during the group stage but saw his participation in the tournament end due to a violent head injury in the early stages of the U.S.’ 1-0 win over Colombia in the Round of 16. Jamieson’s injury left him unavailable for the U.S.' penalty kick defeat to Serbia in the quarterfinals.

On Tuesday, Galaxy head coach Bruce Arena confirmed that 18-year-old suffered a concussion against Colombia, and is currently under evaluation by the club’s medical staff in adherence with the league’s concussion protocol.

“I don’t know when he’s going to be back training,” Arena said. “He’s here though, he was [at the stadium] today.”
