Tottenham boss Antonio Conte will miss Sunday's Premier League game against West Ham and not return to work until he has made an "entire recovery" from surgery to remove his gallbladder.
The 53-year-old had the operation in Italy two weeks ago.
But Conte was back last week before the 4-1 defeat at Leicester and in the dugout for Tuesday's Champions League loss at AC Milan.
In an Instagram post, the Italian said he had "underestimated the procedure".
Conte went on to explain that his "great sense of responsibility towards the club, the players, the staff and the fans" had seen him return too early.
"Sadly, I underestimated the procedure, which wasn't a routine operation, but a sudden and serious emergency," he added.
"My body has suffered my impatience, and now I am forced to stop until my entire recovery.
"Who knows me, understands what a burden this is for me, but it is necessary."
