However, they lost six straight games in March, and finished third in the Atlantic Division with a 44–38 record. The team made the playoffs for the second time with team captain Paul Pierce, but this time as the #6 seed in the Eastern Conference. Pierce and Antoine Walker were both selected for the 2003 NBA All-Star Game. After defeating the 3rd-seeded Indiana Pacers four games to two in the first round, they were unable to stop the New Jersey Nets as they were swept in four straight Conference Semifinal games. This was also Walker's final season with the Celtics, as he was traded along with Tony Delk to the Dallas Mavericks the following offseason. He would return to Boston midway during the 2004–05 season.
