Camarillo left Miami's 48-28 loss to New England in the second half Sunday and did not return. He underwent an MRI on Monday.
"You don't want to lose a player like that," Sparano said. "He's been really productive for us. To me, the guy's been exactly what you're looking for on your football team. I'm disappointed for him. I know how important it is for him."
"He's a very, very consistent player," said Casey Cramer, who has roomed with Camarillo for the past three games. "I just hope that he heals quickly and he gets back out as soon as he can. He's a great guy."
Camarillo did not think the injury was season-ending after Sunday's game, his agent J.R. Rickert said.
"He's in good spirits considering the circumstances," Rickert said. "Greg is the kind of guy who really likes going out there every week and laying it on the line with his teammates."
Camarillo signed a $6 million, three-year extension this year that will keep him under contract through 2011.
"It hurts to lose Greg, but I think we'll be fine," running back Patrick Cobbs said. "I think this team can pick it up and we can definitely move forward."
