Atlanta United centerback George Campbell suffered an adductor injury in the second half of Sunday’s 2-1 loss at Miami and is week-to-week, according to the team.

Campbell appeared to suffer the injury during a collision with Miami’s Gonzalo Higuain.

Campbell, 20, has made eight appearances, including seven starts.

Atlanta United’s other centerbacks are Miles Robinson, Alan Franco and Alex de John.

The team will play at Montreal on Saturday.
