Running back Ahman Green tweaked his groin during Saturday night's preseason game at Arizona and did not practice.
"It's still sore," Sherman said. "I don't think it will be a problem."
Wide receiver Terry Glenn and Robert Ferguson each returned to practice Monday night. Ferguson participated in the entire practice while Glenn dropped out after individual drills.
"We didn't get back home until about 6:30 (a.m.) on Sunday, and playing in that heat, I planned ahead of time if we did a decent job out there; we have such a long week coming up," Sherman said. "If you're not careful, this is a week you can beat your football team up. Just a precautionary measure on my part.
"This is a great opportunity for us to evaluate the younger players. These are critical decisions for us."
Sherman was asked if the Packers have considered re-signing wide receiver Antonio Freeman, since the position has been hit by injuries in the preseason. Freeman, released in June, remains on the free-agent market.
"Haven't considered anything else," Sherman said. "The injuries, at this point, won't keep anyone out of the opener."
