Luca Rossettini's late goal has earned Calgiari a 1-1 draw away to champions Juventus and kept their hopes of Serie A survival alive.
Paul Pogba's strike in first-half stoppage time looked to be enough for the Bianconieri, who are 16 points clear of Roma having already won the Scudetto.
However, Rossettini's equaliser keeps the Sicilians in with a chance of avoiding relegation, although they are still five points from safety.
The away side almost gave their quest for survival an early boost when Diego Farias's ninth-minute effort needed to be stopped by stand-in keeper Marco Storari.
Calgiari then somehow stayed on level terms as Zeljko Brkic pulled off a trio of saves from Pogba, Romulo and Kingsley Coman to keep the visitors in the game.
Pogba finally broke the deadlock for Massimiliano Allegri's men after meeting Simone Padoin's corner to beat the Serbian stopper.
Juve came close to adding another midway through the second half as Romulo fired narrowly wide, but the hosts were made to pay for their missed chances as Cagliari equalised late on.
It came when a free kick from Danilo Avelar was headed onto the post by Rossettini, and the forward tucked home the rebound from close range to earn his side a draw.
