Patrick Willis called himself a game-time decision for Sunday's contest against the Rams.
The 49ers inside linebacker has practiced in a limited fashion throughout the week but said he is still experiencing pain in his left big toe and that he isn't back to 100 percent.
“It's still sore. I can't lie and say I don't feel anything, it feels amazing,” Willis said. “But it's one of those things you have to work through. It could bother me the rest of the season, it could go away. One thing that Cowboy (Justin Smith) says is, if you only played football when you felt good, you'd never play at all. I've always kept that mentality in mind. I'm going to continue to push for it and see what happens on Sunday.”
Willis strained the muscle in the toe Oct. 13 against St. Louis, then missed the following week's game against the Broncos. Rookie Chris Borland filled in for that contest and would do so in Sunday's rematch with the Rams if Willis can't play. Willis and cornerback Tramaine Brock (toe) are listed as questionable on the 49ers' injury report.
That Willis practiced Wednesday-Friday is a good sign. So is the fact that Sunday's game is on grass. Still, he said he would not risk a greater injury by coming back too soon, especially if he feels he can't help his team.
“It's not like having having a broken middle finger where you can put a pad on it and go,” he said. “My feet have made me who I am today.”
Meanwhile, the only 49er who did not practice Friday was running back Marcus Lattimore, who went through his first practices of the season on Wednesday and Thursday. Jim Harbaugh only said that Lattimore, who is coming back from reconstructive knee surgery in 2012, “hung back” in the training room but would not say what him caused him to miss practice.
Asked if soreness was expected after two years of no football-like contact, Harbaugh said, “We'll see exactly what it is and hope to have more information for you.”
