Mike Powell, head wrestling coach at Oak Park and River Forest High School (Oak Park, Ill.), will be one of three coaches featured on the second episode of Sports Illustrated on NBC Sports Network, which will air on Wednesday, Sept. 12 at 9 p.m. ET, with subsequent re-airs throughout the month. The other coaches featured on the episode are football coaches Daron Roberts and Aazar Abdul-Rahim.

Sports Illustrated's Chris Ballard, who wrote a profile story on the Oak Park and River Forest wrestling coach earlier this year, reports on Powell's battle with polymyositis, a rare muscle disorder, and commitment to coaching and mentoring his athletes while battling the disease.

Powell has coached and mentored several wrestlers who have gone on to have success in wrestling after high school, including University of Minnesota wrestlers Chris and Nick Dardanes and 2012 Olympic Greco-Roman wrestler Ellis Coleman.
