Narrative:

Performing touch and go landings; I was on my 3rd and final landing of the day. After touching down near the runway center line; the plane veered right; exited the runway and into the grass between the runway and taxiway. The plane came to a stop when it hit the mud and water in a slight gully. The plane nosed over slightly and the prop struck the mud; causing the engine to stop. No bending of the prop was observed; nor was there any other damage to the airframe or landing gear. I think I might have had my foot too far up on the rudder pedal and was pressing the brake on the right pedal; which caused me to veer off the runway before I could correct. Corrective actions would be to keep feet at bottom of rudder pedals. I also probably had time to correct my trajectory to stay on the runway; but panicked when the plane started veering sharply.

Title: A C172 pilot reported a runway excursion after landing which resulted in the propeller contacting mud and stopping the engine. The pilot may have pressed a brake because his foot was too high on the rudder pedal.
