CSN Bay Area doesn't expect Mario Manningham (ACL surgery) to return before the "latter stages" of camp. Even that might be bullish after Manningham went down in Week 16. Manningham is all but guaranteed to begin camp on the active/PUP list, and a definite candidate to spend the first six games of 2013 on reserve/PUP. Due roughly $4 million between salary and bonuses, it's not a given Manninghamm will be back in San Francisco, though the 49ers' weak receiver corps should work in his favor.
