Saturday’s season-opener against the Iowa Hawkeyes at Ross-Ade Stadium in West Lafayette will be a day of firsts for one of the key members of the Purdue Boilermakers’ coaching staff, co-offensive coordinator/quarterbacks coach Brian Brohm.

With his older brother, head coach Jeff Brohm, expected to miss the game after testing positive for the coronavirus (COVID-19) on Sunday, the younger Brohm is scheduled to serve as the acting head coach and handle play-calling duties, something he said he has never done before.

Brian Brohm, 35, played for the Louisville Cardinals from 2004-08, when Jeff Brohm was an offensive assistant under then-head coaches Bobby Petrino and Steve Kragthorpe.

Following an eight-year professional career, including three seasons in the National Football League with the Green Bay Packers and Buffalo Bills, Brian Brohm joined Jeff Brohm’s staff at Western Kentucky in 2016 as the Hilltoppers’ quarterbacks coach.

When his brother accepted the Purdue job ahead of the 2017 campaign, he followed along and received a new title. Now, the younger Brohm will get his feet wet as an acting head coach with a tough challenge in facing the Iowa Hawkeyes.

The Boilermakers went 4-8 (3-6 Big Ten) in 2019, the worst mark of Jeff Brohm’s tenure thus far. Iowa, meanwhile, enjoyed a 10-3 (6-3 Big Ten) season, including a San Diego County Credit Union Holiday Bowl victory over the USC Trojans.

Saturday’s action will kick at 3:40 p.m. ET on the Big Ten Network.
