Objectives: This multimodal study investigated the motor, neurocognitive and neurophysiological responses following a sports related concussion injury in the acute-phase (up to 10 days) in sub-elite Australian football players. Design: Between-group, repeated measures. Methods: Over the course of one season (six months), 43 male players from one football club (25.1. ?. 4.5 years) were assessed for fine motor dexterity, visuomotor reaction time, implicit learning and attention. Motor cortex excitability and inhibition were assessed using transcranial magnetic stimulation. Results: Of the 43 players, eight suffered concussion injuries, and were compared to 15 non-concussed players (active control) who returned for follow up testing. Post-concussion assessments using the aforementioned tests were carried out at 48 and 96. h, and 10 days. Compared to the non-concussed players, those who suffered concussion showed slowed fine dexterity ( P = 0.02), response ( P = 0.02) and movement times ( P = 0.01) 48. h post-concussion. Similarly, attentional performance was reduced in the concussed group at all time points (48. h: P
