The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Upon rotation, the pilot's seat extended to the aft position causing the pilot to lose directional control of the aircraft and veer right off the runway. The aircraft ended up about 15 feet into the center grass area just north of runway 26R. The aircraft propeller and nose gear had sustained mud contact. The aircraft and pilot sustained no visible damage.
