In the off-season, Cloutier was re-signed to a one-year, $2.5 million contract on July 15, 2003. Nearly two months into the subsequent season, Cloutier recorded his 100th career NHL win, making 31 saves in a 3–1 victory over the Ottawa Senators on November 27, 2003. As the season progressed, Cloutier suffered several more injuries, the first of which was a groin injury in December 2003 that sidelined him for three games. He missed three more games before the season ended with cases of the flu and a lower-body injury. On February 14, 2004, he was fined $1,000 by the league for hitting opposing forward Ronald Petrovický in the face with his blocker during a game against the Atlanta Thrashers.
