Leandro Barbosa took Bradley's spot in the starting lineup.
The Celtics will get an offensive jolt with Barbosa, but take a step back defensively. Boston was 6-2 with a remarkably more consistent (and inspired) defense since Bradley's return at the start of the month.
Celtics coach Doc Rivers said center Chris Wilcox (thumb) will dress again and is available. Wilcox hurt himself in Chicago in mid-December and has dressed the last two games, but the Celtics wanted to get him more practice time before putting him back on the floor.
"He could play. He could have played the last game," Rivers said.
