Koenning, who had been an assistant under MSU coach Dan Mullen for five seasons, arrived in Austin on Tuesday. Texas has yet to officially announce the hiring of Koenning or any other member of Strong's staff.
A former Texas wide receiver and Houston native, Koenning began his coaching career as a graduate assistant at Texas in 1981 and has significant experience coaching and recruiting in the state, including stints at Texas A&M, TCU, Houston and Rice.
He's worked as an offensive coordinator and quarterbacks coach since 1998, with stops at Duke, Houston, TCU, Alabama, Texas A&M and South Alabama before joining Mullen's first staff at Mississippi State.
The Bulldogs set schools records for total yards, passing yards and completion percentage in 2013 and set a new single-season school scoring record last season. Koenning will replace Darrell Wyatt, who coached Texas receivers for three seasons but was not retained.
