"If he gets healthy enough, he'll play in the game even without the practice," Harbaugh said. "I think they have a better handle on exactly what [the injury] is right now. Specifically, they have a good handle on it. It's more muscular. That's good news. If it clears up and he can go, he'll play. If it doesn't, if he can't be close to 100 percent, we'll just have to wait till next week. We're confident in the guys we have as well."
