Maurizio Sarri confirmed Gonzalo Higuain was conscious and lucid after a blow to the head left the Juventus striker needing a stretcher at full-time in a 1-1 draw with Lecce.
Higuain came off worse in an aerial collision with goalkeeper Gabriel late in Saturday's entertaining Serie A match at Stadio Via del Mare.
Medical staff applied bandages to the Argentinian's bloodied head and he completed the match as normal, unleashing multiple shots as the visitors attempted to reclaim the lead.
