Justin Smith has said that his partially torn triceps will not be a concern in the NFC Championship game this weekend.
The 33-year-old told CSN Bay Area: "It's like anything, if it's half-torn or whatever, it could tear the rest of the way.
"I'm not really concerned about it. Just going to go out there and do the best I can and see what happens.
"I think there's still a comfort level of getting used to it. Just mentally going out there and coming out of the game and knowing how it feels and felt during the game. I'll be a lot more comfortable this week."
Smith wore a brace on his arm in the 49ers' win over the Green Bay Packers last weekend.
The 49ers face the Atlanta Falcons in the NFC Championship game on Sunday.
