Pope Benedict XVI hit his head during his March 2012
trip to Mexico, the Vatican says, denying it had any "relevant" role in
his resignation.Italy's La Stampa newspaper reported that Benedict hit his head and bled when he got up in the middle of the night in an unfamiliar bedroom in Leon, Mexico.
The report said blood stained his hair and sheets.
Vatican spokesman the Rev Federico Lombardi confirmed the incident but said "it was not relevant for the trip, in that it didn't affect it, nor in the decision" to resign.
The Vatican newspaper L'Osservatore Romano reported earlier in the week that Benedict had taken the decision to resign after the Mexico-Cuba trip, which was physically exhausting for the 85-year-old pope.
