Palatine High School head football coach Tyler Donnelly resigned Wednesday.
The Daily Herald is reporting that stress-related heart issues were behind the decision. The health issues are reportedly not life-threatening, and were the stimulus for Donnelly to leave the coaching position to spend more time with his wife and two children.
Donnelly led Palatine to one its best seasons in recent history last year, guiding the Pirates to a 10-2 record. Palatine advanced to the state 8A quarterfinals where they lost a tough contest to Loyola.
After working as an assistant coach, Donnelly took over the Pirates in 2005. In his 8 years as head coach, Donnelly compiled a mark of 53-31.
His teams have won the Mid Suburban West title the last two seasons and have appeared in the state playoffs in each of the last six years.
He will continue to teach social studies at Palatine High School.
Jerry Dobbs, Palatine High School athletic director said he will begin to review candidates for the position, and a replacement could be named by February.
