North Dakota State preaches the motto 'next man up' and they mean it.

Sources telling Valley News Live Tuesday morning that the team is hiring former Montana State Offensive Coordinator Courtney Messingham to replace Tim Polasek.

Polasek has been named the offensive line coach at the University of Iowa.

Messingham is now officially listed as offensive coordinator and running backs coach on the Bison website.

With the hiring of Messingham, the Bison will expand current offensive line coach Conor Riley's role to run game coordinator.

Messingham has a deep resume in college football coaching, including time in the Big 12 and the Big Ten. He has served as a head coach and offensive coordinator. He has also coached several different offensive position groups.

He also played college football with NDSU head coach Chris Klieman at Northern Iowa as the two are both Waterloo, Iowa natives.

According to the NDSU website: Courtney Messingham, a 27-year veteran coach with experience in the Big Ten and Big 12 conferences, joined the North Dakota State University football staff as offensive coordinator and running backs coach in February 2017. He has 12 years of previous experience as an offensive coordinator.

Messingham came to NDSU from Montana State, where he was the offensive coordinator and quarterbacks coach in 2016. He was the offensive and special teams quality control coach at Indiana in 2014 and 2015 after spending five seasons at Iowa State from 2009-2013 coaching tight ends (2009-2010), wide receivers (2011) and two years as the offensive coordinator and quarterbacks coach (2012-2013).

He has 10 years of experience at the Football Bowl Subdivision level, but Messingham is no stranger to the Missouri Valley Football Conference. He was a four-year letterman and teammate of NDSU coach Chris Klieman at Northern Iowa from 1986-1989, and the two coached together at Missouri State in 1999. Messingham spent five years at Missouri State in various roles with wide receivers, tight ends, running backs, quarterbacks and special teams from 1999-2002 and again in 2008.

Messingham was part of seven bowl appearances, including three at Southern Mississippi, where he coached wide receivers (2005-2006) and running backs (2007) after two years as the head coach of a Division II reclassifying Upper Iowa program from 2003-2004. He began his coaching career as a graduate assistant at St. Ambrose (1990-1992) before moving on to Iowa Lakes CC (1993-1994) and Truman State (1995-1998).

A native of Waterloo, Iowa, Messingham graduated from UNI with a bachelor's degree in manufacturing and mechanical design in 1990 and earned a master’s degree in business administration from St. Ambrose in 1992.
