Context: Current literature speculates the risks associated with low magnitude head impacts. Objective: The purpose of this study was to record head impact exposures (HIEs) and threshold impacts using the Riddell InSite© accelerometer sensors. Design: Observational cohort. Setting: Data was collected at a Division III College throughout the 2018 season. Participants: Thirty-six football players [18 lineman (LM), 18 backs (BKs), [(age=19.81±1.14years, mass=99.90±17.94kg, height=184.36±5.20cm)] volunteered for this study. Main Outcome Measures: HIEs (low magnitude (LHIE, 15-28Gs), medium magnitude (MHIE, 29-63Gs), high magnitude (HHIE, >63Gs)), threshold impacts (linear and rotational acceleration, location and duration of impact) (95% and 99%), and location of impact. Results: A total of 6986 impacts were sustained with only 2 reported concussions. Independent t-tests revealed significantly (P
