49ers vs. Packers: Jordy Nelson to miss rest of preseason after knee procedure

The San Francisco 49ers face a stiff challenge to start the 2013 season when they host the Green Bay Packers, but the Packers might be joining the 49ers as a bit of a walking wounded when that game rolls around. Per Adam Schefter, Jordy Nelson underwent knee surgery on Monday, and is expected to miss four to six weeks. Four weeks is September 2, and the 49ers and Packers square off September 8. Reports describe it as a procedure to correct a nerve issue that has bothered Nelson since college.

The Packers have solid depth at wide receiver, with Randall Cobb and James Jones prepared to step up as needed. Cobb suffered a biceps injury in practice today, but with over a month until the season starts, odds are he'll be fine.

This all follows yesterday's news that left tackle Bryan Bulaga suffered a torn ACL. Initial reports had him done for the season, but the Packers are still waiting for a second opinion on the injury. Patriots guard Logan Mankins reportedly played the 2011 season on a torn ACL, but there have been no other reports of such a performance. Odds seem good that he will be out when the Packers come to San Francisco, but we'll have to wait and see. For now, rookie David Bakhtiari has replaced him at left tackle in practice.

It's been a busy week for the Packers, as they signed quarterback Vince Young yesterday. This move provides amusement more than anything else. Barring anything unexpected, it should have no bearing on the 49ers Week 1 contest with the Packers. Of course, with Bulaga out, or at least hampered, a big Aldon Smith hit on Aaron Rodgers isn't entirely out of the realm of the possible.
