Evanston High School officials say several members of the baseball team were involved with allegedly forwarding nude or semi-nude photos sent by female classmates.
After talking with each of the players this week, Evanston's athletic director sent a letter to parents of the players.
"We believe that the complicit behavior of the team and the degradation of fellow female classmates is completely unacceptable as representatives of Evanston Township High School. For this reason we do not feel that this team should represent ETHS in the IHSA State Baseball Playoffs," the letter to parents said.
A second letter reaffirms the decision to forfeit the game, effectively ending their season. Some parents complain the decision was unfair and arbitrary.
Experts say sexting is becoming a serious legal issue.
As many as one in five teens has sent a sexually suggestive text message, according to studies cited by the Illinois Bar Association. Those texts often involve nude or semi-nude photos.
