"I don't really know right now," Grubbs said after practice. "I'm just trying to take it one day at a time. Today's rehab and treatment were really big. I made some pretty big steps. So hopefully, tomorrow, I can help. That's what I'm looking forward to."

"We’re OK with him playing without this week of practice," Harbaugh said. "He’s practiced a lot over the years, obviously. He’s our best option, so if he can go, he will. It’s a toe. It’s getting better, it’s not serious, but there’s no guarantee he can play. I’m pretty confident he will play, but we’re just going to have to see. We’re confident in all those guys. We’ll just put those guys out there, they’ve gotten all the reps this week and they’re veteran football players."
If Grubbs cannot play, Andre Gurode could slide in at left guard. Gurode, a five-time Pro Bowler at center, made 38 starts at guard in his first three seasons with the Dallas Cowboys.
"It's just something that we've been working at, and if the team needs me, then I'll fill in," Gurode said.
Grubbs, the organization's first-round pick in 2007, has been the team's starting left guard since the beginning of the 2008 season. Despite his longevity with the team and at that position, he disagreed with the notion that he did not need to practice.
"I'm one of the guys that has to practice," Grubbs said. "But not practicing, the world isn't going to end if I'm not practicing. I think I'll be OK. I think the big thing is, you just have to get mental reps, and that's what I've been doing all week -- studying my game film, studying my playbook, doing the things I can control."
Grubbs said he's played through minor injuries before, but did not go so far as to call this latest ailment minor.
"When people hear 'the toe,' they're like, 'Oh, that's nothing.' But even though it's the smallest part of your body, it's a huge part in running around, pushing off, and blocking -- especially in my position," he said. "It's my first time experiencing this, so I don't really know what to expect. You just hope that -- God willing -- I'll be able to play."
