Fooch's Update: These moves are actually official per the NFL transaction list. The 49ers made the following moves:
To NFI list: Bruce Ellington, Marcus Lattimore, Marcus Martin, Trey Millard, Keith Reaser, Brandon Thomas
To PUP list: Aaron Lynch, Kaleb Ramsey
I'll put together more details, but the PUP list injuries mean those two suffered their injuries during the offseason workout program. The NFI players would be related to college injuries. Again, these are basic procedural moves, and really aren't a huge deal yet because the team can't even go on the practice field until July 24.
ESPN's Field Yates is reporting the San Francisco 49ers will place running back Marcus Lattimore on the Non-Football Injury list to start training camp. He describes it as a procedural move for his rehab process.

If this plays out as Yates describes, it's disappointing we won't get to see Lattimore on the field from day one. However, it is likely a very logical move on the part of the 49ers. Lattimore has been taking part in practice sessions, but on the off chance that something doesn't shake out with his training camp physical, it makes sense to retain the NFI option.
If Lattimore practiced on day one, and then the knee became a problem during that practice or otherwise in the early part of training camp, they would forfeit their use of the NFI list. If I had to guess, I could see Lattimore coming off the NFI list shortly after camp gets going. We can look to Kyle Williams and Kendall Hunter for comparisons. The 49ers placed both men on the PUP list to start training camp on July 20, 2013. They then activated Williams on July 25, and Hunter on August 10.
The only downside to this for now is that we have to wait and see just where Lattimore is at in his rehab progress. All signs have seemed generally positive this offseason, so this is the first potentially negative bit of news. I can see how it would just procedural, but given his injury history, we can't make any assumptions about where he stands. We'll just have to wait and see for now.
