Jenkins started the 2004–05 NBA season on the injured list, but he did see NBA game action 15 times. He was on the bench for the raising of the Pistons' 2004 championship banner, as well as the Pacers–Pistons brawl. Rumors circulated that he was being traded to the Chicago Bulls, and also that he was going to leave the Pistons, and return to Italy. His NBA debut was a two-minute stint against the San Antonio Spurs. He scored 9 points the next night against the New Orleans Hornets. Jenkins scored a career-high 10 points on December 10, 2004, against the Atlanta Hawks. He was one of only three Pistons to score in double figures in that game. He scored 2 points in his hometown of New Jersey on February 5, 2005. Five nights later, in a rematch of the 2004 NBA Finals, Jenkins scored 8 points, in only 6 minutes against the Los Angeles Lakers. He scored 6 points in 20 minutes in his final NBA game, which was against the Charlotte Bobcats.
