On the first two plays of the 49ers' second possession of the day, Gore ripped off a 19-yard run off of left guard, and then Davis got loose on a wheel route behind Buffalo's secondary on a play fake for a massive 53-yard gain. That set San Francisco up deep in Bills territory.
Mercifully, Buffalo's defense stiffened at that point in time. Faced with a 2nd & Goal on the one-yard line, linebacker Nick Barnett stuffed Gore on two short-yardage attempts (with help from teammates on both plays, of course), and the 49ers were forced to settle for a 19-yard field goal from David Akers.
Leodis McKelvin, who has already had a punt return for a touchdown called back due to penalty, returned the ensuing kickoff into 49ers territory. Buffalo's offense is looking to improve on their first drive, when they went three-and-out.
