Pierce came out of the game while trainer Tim Walsh worked on his shoulder, but returned in the fourth.
“It’s been a problem for me throughout the last few years,” said Pierce, who was also briefly forced out of Wednesday night’s game because of the injury. “It’s weak right now, so whenever I get hit in that shoulder ... just with the constant years of banging, especially now that I’m playing the four. So it’s a quick stinger.”
• Pierce, who spent the first 15 seasons of his career in Boston, was asked if he’d ever play for the Celtics again.
“Yeah, why not?” he replied. “Maybe play for them, maybe work for them. Who knows what the future holds.”
Pierce is in the last year of his contract ($15.3 million) and will be an unrestricted free agent at season’s end.
The Nets hold his full Bird Rights, meaning they could exceed the salary cap to re-sign him.
