Due to World War II, Missouri State did not field a team for the 1943–1944 seasons.

After the 1991 renovation which added an upper deck on the west side and a row of sky-boxes and press box, the stadium was renamed in honor of Robert W. Plaster who provided the major gift for the project.

In July 2018, it was reported that Missouri State was undergoing the process of securing funding to build an indoor practice facility.

In a phone interview with the Springfield News-Leader, athletic director Kyle Moats talked at length about the facility.

Missouri State would build the indoor facility entirely through private donations to the athletic department.

He said the athletic department wasn't able to achieve the funding they needed to build the facility as some other programs became more important to address first.

Moats said that the facility would be used by the club lacrosse team, football, soccer, track and field, baseball and softball.

In the interview Moats said "We wouldn't be gaining any traction, we'd just be catching up," and "We're not trying to have the Taj Mahal, just an indoor facility.

In late October 2021, Missouri State announced plans to build a facility in the south end zone of Plaster Stadium.
