Providence Catholic High School in New Lenox, Illinois, has parted ways with football coach Tyler Plantz despite the Celtics opening the 2026 season with a perfect 4 0 record.
The decision has surprised players, parents, alumni and members of the school community, particularly because Providence Catholic entered the week ranked No. 1 in Class 5A.
Plantz, who was in his fifth season as head coach, said he was asked by a school official to resign following the team’s 31 7 victory over Carmel Catholic during homecoming weekend. When he declined, he said the school dismissed him.
“I was surprised, definitely, that it happened,” Plantz told CBS News Chicago.
Plantz said several reasons were discussed during the meeting, including issues he believed could have been addressed. He did not identify a specific incident that led to his dismissal.
The school also has not publicly provided a detailed explanation for the decision.
Coach Says His Focus Remains on Players
Providence Catholic announced the coaching change in a statement thanking Plantz for his service and commitment to the school’s student-athletes and football program since 2022.
Offensive coordinator Adam Nissen will serve as interim head coach for the remainder of the season.
The timing of the decision has led to questions among members of the Providence community. Plantz had guided the Celtics to a 4 0 start this season and compiled a 35 19 record during his five years leading the program.
During his tenure, Providence Catholic also reached two state championship games.
Plantz said he has received numerous messages and calls from supporters since the announcement. However, he stressed that his priority is making sure the players remain focused on their season.
“It’s never been about me,” Plantz said. “I want to make sure the focus stays on the guys.”
The coach also said he does not want his departure to become a distraction for the team as the Celtics continue their undefeated campaign.
A Deep Connection to Providence Catholic
Plantz’s connection to Providence Catholic goes well beyond his coaching career. He attended the school and later played football at the University of Notre Dame, where he eventually worked as a coach.
He returned to Providence after his brother, Zak Plantz, died in a 2020 car crash.
Plantz said his family also contributed money toward the school’s weight room, which was named the Zak Plantz Performance Center. The experience played a role in his decision to leave Notre Dame and coach at his alma mater.
Despite the circumstances surrounding his departure, Plantz said he remains grateful to Providence Catholic and considers himself a Celtic at heart.
“Providence has done so much for me and my family,” he said.
The Celtics now move forward under Nissen as they attempt to maintain their undefeated season. The school has not publicly detailed the circumstances behind Plantz’s firing, leaving the coaching change as one of the most unexpected developments of the young Illinois high school football season.
