One 49ers offensive lineman, tackle Anthony Davis, is on hand for the 49ers' third and final practice of the week. Another, guard Mike Iupati, is not after suffering a concussion inMonday's win over the Rams.
Iupati has until Sunday to pass the final stage of the league-mandated post-concussion protocol, which involves simulated contact. Iupati has been working out in the team's weight room as practice has begun this week.
Meanwhile, Patrick Willis (foot) and Jimmie Ward (quad) are not practice and are unlikely to play Sunday in Denver. Receiver Stevie Johnson (hip) has been practicing on a limited basis this week.

The 49ers continued their game of musical roster spots today by signing Ray Ventrone and cutting quarterback Josh Johnson. The 49ers made the reverse move – cutting Ventrone, a special teams player – and signing Johnson earlier in the week. The process is likely to be repeated next week.
The situation essentially allows the 49ers to have 54 players on the roster. Ventrone, a veteran who has spent several seasons with special teams coordinator Brad Seely, does not need to be on hand for practice. Johnson, the team's No. 3 quarterback, is useful in practice but does not suit up on game day.
The 49ers might be more hesistant to cut Johnson after Oct. 28 when he would be subject to waivers.
