Camby was hurt when Nets center Brook Lopez stepped on his ankle as both waited for a rebound a little more than 5 minutes after the opening tip.
X-rays were negative and coach Nate McMillan did not think the injury was serious.
"I contested a shot [by Devin Harris] and I think Lopez stepped on my ankle," Camby said. "My momentum went the other way. It is pretty sore right now."
"Hey, Camby, welcome to Portland," McMillan said referring to the Trail Blazers' injury-plagued season. "It's amazing what our guys are going through. I think he's going to be OK."
Brandon Roy could only shake his head after the game.
"Is our center spot cursed?" he said.
