In a statement, lawyer Scott Wilhelm says the eight Phillipsburg High School wrestlers will address their school's "supervision" of their participation in a tournament that starts this week.
Phillipsburg officials would not disclose why the wrestlers were pulled from competition, saying they cannot comment on any "student issues."
The picture posted online showed seven boys in Phillipsburg wrestling attire surrounding a black wrestling dummy wearing a rival Paulsboro High School T-shirt and hanging from a noose.
The state Division on Civil Rights is looking at the case.
