MINNEAPOLIS (AP) - Nick Novak's 45-yard field goal as time expired gave the San Diego Chargers a 12-10 victory on Friday over Minnesota, after Vikings quarterback Christian Ponder struggled along with the rest of the starting offense.

Nate Kaeding made field goals of 50 and 54 yards for the Chargers (No. 16 in the AP Pro32 rankings). Novak, the token training camp competitor who'll most likely be cut next week, kicked two of his own.

Sage Rosenfels threw a late touchdown pass to Matt Asiata, who lost one of three Vikings fumbles earlier in the second half.
