Brock Ervin joins the Fighting Illini coaching staff in 2017-18 as a student volunteer coach after multiple knee injuries cut his wrestling career short. 

After tallying 21 wins as a redshirt in 2014-15, Ervin started for the Illini at 141 each of the next two seasons. In 2015-16, Ervin finished with an 8-5 record, highlighted by a 14-12 upset of No. 12 Steve Bleise at Northern Illinois. After an injury cut the end of his season short, Ervin bounced back in 2016-17 with a 13-3 record to start the season only to see his season again ended due to injury. Overall, Ervin finished his Illini career with a 21-8 record with five of the victories coming by fall.  

Off the mat, Ervin excelled in the classroom. A two-time Academic All-Big Ten honoree, Ervin was also named an Academic All-American by the National Wrestling Coaches Association in 2015-16. 

A product of Union Country High School in Morganfield, Kentucky, Ervin won five state titles, going undefeated against opponents from the state of Kentucky. He was a part of two Union County High School state championship teams and was named the team's Most Outstanding Wrestler as a senior.
