(CBS) Once the star figure in leading the Bulls in the playoffs, Derrick Rose was in the same environment Sunday night but in a much different role.

Rose was in attendance at the United Center to watch the Celtics beat the Bulls, 104-95, in Game 4 of their first-round series. Rose took a seat in the front row along the baseline for the second half, flanked by his young son, P.J.

Rose played his first eight seasons in Chicago, where he was named the league MVP in 2011 and led the Bulls to the Eastern Conference finals. After a string of devastating knee injuries, Rose was traded to the Knicks last June in a deal that brought Robin Lopez and Jerian Grant to the Bulls.

After his Knicks missed the postseason, Rose attended the Bulls-Celtics game a night after attending the Grizzlies-Spurs game in Memphis because he likes being amid the playoff atmosphere, he told the Tribune.

Rose received a big ovation from the United Center crowd when he was shown on the video board along with other former Bulls players in attendance.
