Torino coach Giampiero Ventura was checked by medics following his side's 4-2 defeat to AC Milan at home in Serie A.
The 64-year-old felt unwell during the game and asked his assistant Salvatore Sullo to conduct the team's play from the touchline while he sat in the dugout for the second half.
Ventura failed to recover his health by the end of the match and was subsequently checked by the ambulance staff at the stadium.
"The coach felt unwell but everything is fine now," said Sullo. "It was nothing in particular and now he will go home to rest."
Ventura was appointed the Torino coach in 2011.
