A league source confirmed last night Rajon Rondo and Paul Pierce were fined for missing their NBA Day of Service appearances during All-Star weekend in Orlando, Fla.

A USA Today report listed the fines — also assessed to Kobe Bryant — at $20,000 apiece, though the source would not confirm the amount.

Rondo declined comment, saying, "If I talk about it, they'll just fine me again."

This is not the first time the Celtics have fumbled their Day of Service commitment. Last season in Los Angeles, Pierce, Rondo, Kevin Garnett and Ray Allen all did not show up for their scheduled public service appearances, much to the chagrin of Doc Rivers, who did honor his commitment and later noted LeBron James drove himself to the work site. (Allen said a sudden schedule change by the NBA led to the four absences.)
