The John Deitrich Field House, located across the corridor from Memorial Hall, was constructed in 1982 and refurbished in 2004.

The spacious field house hosts tennis matches when weather precludes outdoor play and is the winter home of the track and field teams.

The facility serves as a secondary practice area for all Muhlenberg teams. A netting system installed in 2004 enables multiple teams to practice safely at the same time.

The four-lane, 160-meter track was resurfaced in 2004 and now features the same polyurethane surface as the outdoor track. A jump pit and a pole vault box were also added, enabling the Mules to host limited indoor meets.
