The Pro Bowl linebacker has missed just six games in his 11-year NFL career. He was unable to finish last Sunday's game at San Diego when his right hamstring tightened.
"In this situation, I'm just waiting," Porter said. "I look at myself as a competitive guy and warrior. If there's any way I can be on the field, I'm going to be on the field. If I can play 80 percent, or whatever the situation may be, hurt or whatever, I'll play. That's just how I go. I don't miss games that I can play in."
The Dolphins take an 0-3 record into the game.
"We feel that if we stop beating ourselves, we can play with anybody," Porter said. "But until we do that, we're going to run into problems."
