Big 12 fans will have to learn a new name to curse at when officials blow a call in a game this fall.

Speaking at Big 12 spring meetings in Arizona on Wednesday afternoon, Commissioner Bob Bowlsby confirmed that the conference’s Coordinator of Football Officials Walt Anderson has submitted his resignation and will no longer be involved with the league. A replacement is expected to be found over the coming months and announced later this summer.

Anderson had been pulling double-duty for years in splitting his time between the Big 12 and the NFL, where he was a recognizable face on Sundays. He was hired last fall to be a full-time official with the league office but continued to perform his duties at the college level.

That arrangement didn’t last long.
