Antonio Chimenti is facing a spell on the sidelines after breaking his hand by punching a table.
The veteran Juventus goalkeeper lashed out in frustration after Antonio Cassano's late strike sealed a 1-0 victory for Sampdoria in Serie A on Sunday.
The 39-year-old was playing in only his third game since returning to Juve in 2008 but will not now be available for some time.
Fortunately Alex Manninger is back to full fitness and should be able to take his place between the sticks against Napoli on Thursday, while first-choice keeper Gianluigi Buffon has also returned to training.
"I was very upset, I was first back into the dressing room and I vented my anger with a punch on the table," said Chimenti, who is behind both Buffon and Manninger in the pecking order.
"Unfortunately I broke my hand.
"For Thursday both of them (Buffon and Manninger) should be back. I'm very upset not to be there but I am happy for them and for the squad for their return."
Chimenti was not the only Juve player upset by the defeat to Sampdoria, which followed on from a painful Europa League exit at the hands of Fulham.
The players have asked for an extra day's preparation as they look to improve on their current position of sixth in the table and secure UEFA Champions League qualification.
Captain Alessandro Del Piero said: "We asked to go to training camp so we could spend a bit of time together, to rediscover our physical and mental energies.
"It was a devastating week, from the game against Siena to the exit from the cup, to Cassano's great goal in an evening where we were equal to each other until that time.
"We took a harsh blow. There are still nine games left and we can't make any more mistakes.
"It's a pity, with Zac we were recovering, in seven days we have ruined a month and a half of work."
Alberto Zaccheroni, who replaced the sacked Ciro Ferrara as manager in January, admits he will be disappointed in himself if Juve fail to qualify for the Champions League.
"If we don't succeed in getting to fourth place that means that I have failed in my mission," he said.
"This is a squad which has to rediscover its strengths. I think we are still on course for fourth place.
"Inside the dressing room there is no desire to finish a season by failing, instead there is a desire to redeem themselves.
"Certainly, right up until the end, we will never give up: both me and the squad see it as a challenge to win."
